10. Using a leak detection solution or soap suds, check
for leaks at the pressure outlet boss and pressure
tap test screw.

High Altitude Derate
Input ratings (BTUH) of these Furnaces are based on
sea level operation and should not be changed at
elevations up to 2,000 ft. (610 m).
If the installation is 2,000 ft. (610 m) or above, the
Furnace input rate (BTUH) shall be reduced 4% for each
1,000 ft. above sea level.
Installations of this furnace at altitudes above 2,000 ft.
(610 m) shall be made utilizing the Vent Length table
and/or Part Numbers for Replacement Orifices table in
these installation instructions.
The Furnace input rate shall be checked by clocking the
gas flow rate (CFH) and multiplying by the heating
value obtained from the local utility supplier for the gas
being delivered at the installed altitude. Input rate
changes can be made by adjusting the Manifold
Pressure (min 3.0 - max 3.7 in. W.C. - Natural Gas) or
changing orifices (orifice change may not always be
required).
If the desired input rate can not be achieved with a
change in Manifold Pressure, then the orifices must be
changed. Propane installations will require an orifice
change.
IImmppoorrttaanntt:: Reinstall the replacement orifices to the
same depth as the orifices supplied with
the equipment.
See the table for help in selecting orifices if orifice
change is required. Furnace input rate and temperature
rise should be checked again after changing orifices to
confirm the proper rate for the altitude.
The vent length table shows the required vent lengths
for installations at various altitudes. Installations above
12,000 feet are not allowed.

Turn the main Gas Valve toggle switch within the unit
to the "OOFFFF" position. Turn the external gas valve to
"ON". Purge the air from the gas lines. After purging,
check all gas connections for leaks with a soapy
solution DDOO NNOOTT CCHHEECCKK WWIITTHH AANN OOPPEENN FFLLAAMMEE..
Allow 5 minutes for any gas that might have escaped to
dissipate.
Propane Gas being heavier than air may require forced
ventilation. Turn the toggle switch on the Gas Valve in
the unit to the "ON" position.
The table in next page lists the main burner orifices
used with the furnace. If a change of orifices is required
to correct the furnace input rating refer to the part
number for replacement orifices table.
Installation of this furnace at altitudes above 2000 ft
(610m) shall be in accordance with local codes, or in
the absence of local codes, the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 or National Standard of Canada,
Natural Gas and Propane Installation Code, CSA
B149.1.
