Gas Connection
IMPORTANT: The installation must comply with
local codes, the current National Fuel Gas Code,
ANSI Z223.1 in the U.S.A., or the current CAN/
CSA B149, Installation Codes in Canada.
Install a shut-off valve to isolate gas connections from
rest of installation. Gas models must be connected to
the existing gas pipes. The gas supply pipe size must
have sufficient dimensions to minimize pressure loss.
Obtain specific gas supply pipe size from the gas
supplier. Refer to
Table 5 for general pipe size.
When connecting to a gas line, an equipment shut-off
valve must be installed within 6 feet (1.8 m) of the
finisher. A 1/8 inch N.P.T. pipe plug must be installed
as shown. Refer to
Figure 4 .

IMPORTANT: For L.P. (Liquefied Petroleum) gas, correct the total BTU/hour by multiplying it by 0.6. The
answer is the equivalent BTU on the above chart.
