SPECIFIC SAFETY RULES AND PRECAUTIONS
1.
Only Natural gas or Propane (LP) gases are approved for
use with this furnace. Refer to the furnace rating plate or
SECTION IV of these instructions.
2.
Install this furnace only in a location and position as
specified in SECTION II of these instructions.
3.
A gas fired furnace for installation in a residential garage
must be installed as specified in SECTION I of these
instructions.
4.
Provide adequate combustion and ventilation air to the
furnace space as specified in SECTION VI of these instructions.
5.
Combustion products must be discharged outdoors.
Connect this furnace to an approved vent system only, as
specified in SECTION VI of these instructions.
6.
Tests for gas leaks as specified in section IX of these
instructions. Never test for gas leaks with an open flame.
7.
Always install furnace to operate within the furnaces
intended rise range with a duct system that has an external static
pressure within the allowable range, as specified in these
instructions. See furnace rating plate.
8.
When a furnace is installed so that the supply duct(s) carry
the air circulated by the furnace to areas outside the space
containing the furnace, the return air shall also be handled by
duct(s) sealed to the furnace casing and terminating outside the
space containing the furnace.
9.
The return air duct system is not required by the
manufacturer provided the combustion air and vent system have
been installed as a Two Pipe Sealed Combustion System and
provided a return air duct system is not required by state, local
or regional codes. Refer to sealed combustion systems section in
ANSI 223.1 (NFPA 54) – latest edition.
10.
It is permitted to use the furnace for heating of buildings or
structures under construction. Installation must comply with all
of the manufacturer’s instructions including:
Proper vent installation.
Furnace must be operating under thermostatic control.
Return air duct must be sealed to the furnace.
Air filters must be in place.
Set furnace input rate and temperature rise per the
rating plate marking.
Means for providing outdoor air required for
combustion.
Return air maintained between 55°F (13°C) and 80°F
(27°C).
The air filter must be replaced upon substantial
completion of the construction process.
Clean furnace supply and return air duct work making
sure the duct system is free of saw dust, dirt, dust and
debris. Clean all of the furnace components upon
substantial completion of the of the construction
process.
Verify furnace operating conditions including:
Ignition
Input rate
Temperature rise
Venting system
Verify the furnace is operating according to the
manufacturer’s instructions.
11.
When installed in a Manufactured (Mobile) Home:
The
combustion air shall not be supplied from occupied spaces.
12.
The size of the furnace shall be based on an acceptable heat
loss calculation for the structure. ACCA Manual “J” or other
approved methods may be used.
13.
Gas fired heating equipment must be vented - do not
operate unvented
14.
If you are replacing an existing furnace, it may be necessary
to replace the roof jack venting system. Improperly sized or the
wrong roof jack venting system can result in vent gas leakage or
the formation of condensate. Refer to the National Fuel Gas
Code ANSI Z223.1 or CAN/CGA B149.1 or .2 latest editions.
Failure to follow these instructions can result in injury or death.
15.
To reduce the opportunity for condensation, the minimum
sea level input to the appliance, as indicated on the rating plate,
must not be less than 8% below the rated input.
16.
Ensure that the supply voltage to the appliance, as indicated
on the rating plate, is not 5% greater than the rated voltage.
17.
Manufactured (Mobile) Home Installation:
This
appliance must be installed and maintained as a Two Pipe
Sealed Combustion Configuration. The combustion air pipe
must terminate in the same atmospheric zone as the vent pipe
and they must terminate external to the building.
18.
Roof Jack Sizes
:
Mortex is a 4” Vent Pipe with a 7” Combustion Air Pipe.
Coleman is a 5” Vent Pipe with a 8” Combustion Air Pipe.
Nordyne is a 5” Vent Pipe with a 8” Combustion Air Pipe.
If you replace a Coleman or Nordyne furnace with a Mortex and
do not change the vent the furnace will fire up for around 5
seconds to a minute and the flame will extinguish,
19.
Modular Homes:
This appliance can be installed in one of
the following configurations:
a.
A Two Pipe Sealed Combustion Configuration. This
configuration has a combustion air pipe and a vent pipe that
terminates in the same atmospheric zone and is external to
the building. Refer to Figures 19 – 25.
b.
A One Pipe Vent with Ambient Combustion Air
Configuration. This configuration has no combustion air
pipe connected to the burner box. The vent pipe terminates
external to the building.
c.
A One Pipe Ventilated Combustion Air Configuration: This
configuration has the combustion air pipe connected to the
burner box and terminating in the attic or a crawl space.
The vent pipe terminates external to the building. The vent
FIRE OR EXPLOSION HAZARD
Failure to follow the safety warnings exactly could result in
serious injury, death or property damage. A fire or
explosion may result causing property damage, personal
injury or loss of life.
Never test for gas leaks with an open flame. Check all gas
piping connections with a commercially available soap
solution
made
specifically
for
detection
of
leaks.
