LIMITATIONS
These units must be installed in accordance with the follow-
ing:
In U.S.A.:
1. National Electrical Code, ANSI/NFPA No. 70 - Latest
Edition
2. National Fuel Gas Code, ANSI Z223.1 - Latest Edition
3. Gas-Fired Central Furnace Standard, ANSI Z21.47a. -
Latest Edition
4. Local building codes, and
5. Local gas utility requirements
In Canada:
1. Canadian Electrical Code, CSA C22.1
2. Installation Codes, CSA - B149.1.
3. Local plumbing and waste water codes, and
4. Other applicable local codes.
Refer to Tables 1 & 2 for unit application data.
After installation, gas fired units must be adjusted to obtain a
temperature rise within the range specified on the unit rating
plate.
If components are to be added to a unit to meet local codes,
they are to be installed at the dealer’s and/or customer’s
expense.
Size of unit for proposed installation should be based on heat
loss/heat gain calculation made according to the methods of
Air Conditioning Contractors of America (ACCA).
This furnace is not to be used for temporary heating of build-
ings or structures under construction.
This product must be installed in strict compliance with
the enclosed installation instructions and any applica-
ble local, state and national codes including, but not
limited to, building, electrical, and mechanical codes.
The furnace and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing at pressures in excess of 1/2
PSIG.
Pressures greater than 1/2 PSIG will cause gas valve
damage resulting in a hazardous condition. If it is sub-
jected to a pressure greater than 1/2 PSIG, the gas
valve must be replaced.
The furnace must be isolated from the gas supply pip-
ing system by closing its individual manual shut-off
valve during any pressure testing of the gas supply pip-
ing system at test pressures equal to or less than 1/2
PSIG.
