____________________________

CAUTION: The available gas pressure should be within the limits shown in

Table 1 - SPECIFICATIONS section. Excessive pressure may damage electric valves,
regulators and manual valves. If the supply pressure exceeds the 14.0"W.C. maximum,
a suitable high pressure regulator must be installed between the Main Manual
Shut-Off Valve and burner combination valve. 

The  burner gas supply piping should branch off from the main line as close to the gas

meter as possible. Do not connect to the bottom of a horizontal section. Use new black pipe
and malleable fittings free of cutting and threading burrs or defects.

Piping must also comply with your local codes.

To obtain the maximum firing rate of the burner, the  gas supply piping must be sized to

provide a minimum pressure of 7.0"W.C. (Natural) for 400 MBH to the inlet of the combination
redundant valve when the burner and all other gas utilization equipment are on refer to table
# 3 for 350 MBH and 250MBH gas pressure requirments. The main regulator, if equipped,
should be mounted upright and in a horizontal run of pipe, refer to regulator manufacturer’s
installation instructions.

CAUTION:  Because it is difficult to accurately control pressure during supply

pipe leak testing, it is recommended that all low pressure 1/2 PSIG (14.0"W.C. max.)
components be disconnected during testing. Exposing low pressure regulators and
valves, including manual valves, to pressures over 1/2 PSIG (14.0"W.C.) will cause
damage and void all warranties.
