REQUIREMENTS & CODES

• This furnace must be installed in accordance with 

these instructions, all applicable local building codes 

and the current revision of the National Fuel Gas Code 

(NFPA54/ANSI Z223.1) or the Natural Gas and Propane 

Installation Code, CAN/CSA B149.1.

• Use only with type of gas approved for this furnace. 

Refer to the furnace rating plate.

• Install this furnace in accordance to the minimum 

clearances to combustible materials listed in 

Table 1, 

(page 6)

.

•  Provide adequate combustion and ventilation air to the 

furnace space as specified on 

page 7

Do not block 

or obstruct air openings on the furnace, air openings 

to the area where the furnace is installed, or the space 

around the furnace.

• Combustion products must be discharged outdoors. 

Connect this furnace to an approved vent system, as 

specified on 

page 10

.

• Never test for gas leaks with an open flame. Use 

a commercially available soap solution to check all 

connections. See 

page 17

.

• This furnace is designed to operate with a maximum 

external pressure rise of 0.3 inches of water column. 

NOTE 1:

 The static pressure measurement should not 

include the coil (if applicable). Consult the rating plate 

for the proper circulating air flow and temperature rise.

 

NOTE 2:

 It is important that the duct system be designed 

to handle the desired flow rate and external pressure 

rise. An improperly designed duct system can result in 

nuisance shutdowns, and comfort or noise issues.

•  When supply ducts carry air circulated by the furnace 

to areas outside the space containing the furnace, the 

return air shall also be handled through the front door 

of the furnace. Make sure there is sufficient return air 

through the door. See return air connections 

page 7

• The Commonwealth of Massachusetts requires 

compliance with regulation 248 CMR 4.00 and 5.00 for 

installation of through – the – wall vented gas appliances 

as follows:

1. For direct-vent appliances, mechanical-vent heating 

appliances or domestic hot water equipment, where the 

bottom of the vent terminal and the air intake is installed 

below four feet above grade the following requirements 

must be satisfied:

a.) A carbon monoxide (CO) detector and alarm shall be 

placed on each floor level where there are bedrooms. 

The detector shall comply with NFPA 720 (2005 

Edition) and be mounted in the living area outside 

the bedroom(s).

b.) A (CO) detector shall be located in the room that 

houses the appliance or equipment and shall:

• Be powered by the same electrical circuit as the 

appliance or equipment. Only one service switch shall 

power the appliance and the (CO) detector;

•  Have battery back-up power;

• Meet ANSI/UL 2034 Standards and comply with 

NFPA 720 (2005 Edition); and Approved and listed 

by a Nationally Recognized Testing Laboratory as 

recognized under 527 CMR.

c.)  A Product-approved vent terminal must be used, and 

if applicable, a product-approved air intake must be 

used. Installation shall be in strict compliance with the 

manufacturer’s instructions. A copy of the installation 

instructions shall remain with the appliance or 

equipment at the completion of the installation.

d.) A metal or plastic identification plate shall be mounted 

at the exterior of the building, 4 feet directly above 

the location of vent terminal. The plate shall be of 

sufficient size, easily read from a distance of eight 

feet away, and read “Gas Vent Directly Below”.
