15.1

This appliance shall not be installed in a confi ned space or unusually tight construction unless provisions are provided for 

adequate combustion and ventilation air.

The National Fuel Gas Code, ANSI Z223.1 

/ NFPA 54

 defi nes a confi ned space as a space whose volume is less than 50 

cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space 

and an unconfi ned space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3  per 

kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space 

in which the appliances are installed, through openings not furnished with doors are considered a part of the unconfi ned 

space. 

To determine the volume of  the room where the appliance is to be installed, multiply the width x the length x the ceiling 

height of that room measured in feet. If any adjoining rooms are connected by grilles or openings such as kitchen pass-

throughs, etc., the volume of those rooms may be added to the total. 

Multiply the room volume by 1000 and divide this amount by 50 to determine the maximum BTU/hr that the space can 

support with adequate combustion and ventilation air.

Add the Btu/hr of all fuel burning appliances located within the space such as gas furnace, gas water appliance, etc. 

Do not include direct vent gas appliances which draw their input air from the outdoors and expel their exhaust to the 

outdoors.

Unusually tight construction is defi ned as construction where:

A)

  Walls and ceilings exposed to the outside atmosphere have a continuous water vapour retarder with a rating of 1 

perm (6 x 10-11 kg per pa-sec-m2) or less with openings gasketed or sealed

B)

   Weather stripping has been added on openable windows and doors

C)

   Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and 

fl oors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at 

other openings.

An unvented room appliance is recommended for use as a secondary heat source rather than as a primary source. Gas 

combustion produces water vapour which could occur at the rate of approximately one ounce of water for every 1,000 

BTU/hr of gas input. During the cold weather season, indoor humidity levels tend to be low. Consequently, this water 

vapour can enhance the living space. However if a problem should occur:

A)

  Ensure suffi cient combustion and circulation air

B)

  Use a dehumidifi er

C)

   Do not use the unvented room appliance as a primary heat 

source. Without suffi cient fresh air for proper operation, poor fuel 

combustion can result. Carbon Monoxide is a result of poor fuel 

combustion.

If additional fresh air is required, use one of the methods 

described in the National Fuel Gas Code, ANSI Z223.1 / NFPA54 

or the applicable local code.

Room Volume = Length x Width x Height

Max BTU/hr = Room Volume x 1000 / 50

If for example:

The length of the rooms is 5 feet (1.5m),

The width of Room 1 is 10 feet (3.1m),

The width of Room 2 is 15 feet (4.6m),

The height of the rooms is 8 feet (2.4m).

Volume of Room 1: 5x10x8 = 400 cubic feet (11.16 cubic meters)

Volume of Room 2: 5x15x8 = 600 cubic feet (16.56 cubic meters)

EXAMPLE 1:

In this example, because there is no door to the adjoining room, the volume of the adjoining room may be added to the 

volume of the room with the heater to get a total unconfi ned space.

The total unconfi ned space: 400 ft

 (11.3m

3

)+ 600 ft

 (17m

3

) = 1000 cubic feet (28.3m

3

).

Maximum BTU/h: [(1000x1000) ÷ 50] = 20,000 BTU/h

EXAMPLE 2:

If in this example a solid door separates Room 1 from Room 2, the volume of Room 2 could not be used. In this case the 

maximum BTU/h would be:

Maximum BTU/h: [(400x1000) ÷50] = 8,000 BTU/h

•  If the area in which the appliance may be operated is smaller than that defi ned as an unconfi ned space or if 

the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the 

methods described in the National Fuel Gas Code ANSI Z223.1 / NFPA 54, air for combustion and ventilation, 

or the applicable local code.

•  If the area in which the appliance may be operated does not meet the required volume for indoor combustion 

air, combustion and ventilation air shall be provided by one of the methods described in the ANSI Z223.1 / 

NFPA 54, the International Fuel Gas Code, or applicable local codes.

!

WARNING

If there are no more fuel burning appliances within this space then the 30,000 BTU/h input of the appliance is suit-

able to be installed. This also assumes that the construction of this space is not unusually tight.

WARNING

This would be considered a confined space since it can not support the 30,000 BTU/h input of the appliance and 

it would be necessary to provide adequate combustion and ventilation air to Room 1.

2.1  gas installation

21.1

!

WARNING

•  Risk of fi re, explosion, or asphyxiation. Ensure there are no ignition sources such as sparks or open fl ames.

•  Support gas control when attaching gas supply pipe to prevent damaging gas line.

•  Always light the pilot whether for the fi rst time or if the gas supply has run out with the glass door opened 

or removed. Purging of the gas supply line should be performed by a qualifi ed service technician. Ensure 

that a continuous gas fl ow is at the burner before closing the door. Ensure adequate ventilation. For gas and 

electrical locations, see “dimensions” section.

•  All gas connections must be contained within the appliance when complete 

(gas fi replaces only)

.

•  High pressure will damage valve. Disconnect gas supply piping before testing gas line at test pressures above 

1/2 PSIG.

•  Valve settings have been factory set, do not change.

Installation and servicing to be done by a qualifi ed installer.

•  Move the appliance into position and secure.

•  If equipped with a fl ex connector, the appliance is designed to accept a 1/2” (13mm) gas supply. Without the 

connector, it is designed to accept a 3/8” (9.5mm) gas supply. The appliance is equipped with a manual shut 

off valve to turn off the gas supply to the appliance.

•  Connect the gas supply in accordance to local codes. In the absence of local codes, install to the current 

CAN/CSA-B149.1 Installation Code in Canada or to the current National Fuel Gas Code, ANSI Z223.1 / NFPA 

54 in the United States.

•  When fl exing any gas line, support the gas valve so that the lines are not bent or kinked.

•  The gas line fl ex-connector should be installed to provide suffi cient movement for shifting the burner assembly 

on its side to aid with servicing components.

•  Check for gas leaks by brushing on a soap and water solution. 

Do not use open fl ame.

2.2  optional wall switch / thermostat

34.1

!

WARNING

•  Do not connect either the wall switch, thermostat or gas valve directly to 110 volt electricity.

For ease of accessibility, an optional remote wall switch or millivolt thermostat may be installed in a convenient  

location. Route a 2 strand, solid core millivolt wire from the valve to the wall switch or millivolt thermostat. The 

recommended maximum lead length depends on wire size:

 

WIRE SIZE 

 

MAX. LENGTH

 

14 gauge (1.8mm) 

100 feet (30.5m)

 

16 gauge (1.5mm) 

  60 feet (18.3m)

 

18 gauge (1.2mm) 

  40 feet (12.2m)

Disconnect the existing wires from terminals 1 and 3 (from the

ON/OFF switch) and replace with the leads from the wall switch / millivolt thermostat.
