5. CONNECT GAS PIPING
Size gas piping according to Appendix C – Gas
Piping
SHUT OFF GAS SUPPLY before
servicing the boiler.
ALL GAS PIPING MUST BE GAS
TIGHT. Use gas rated thread compound
on all threaded joints to avoid leaks, which may
result in re or explosion.
SIZE GAS PIPING, regulators, valves,
and meters so as to provide an adequate
gas ow and pressure to the boiler during
operation. Failure to do so may cause poor
combustion, noise, injury, or death.
1. Remove boiler door, locate gas valve and
remove plastic shipping plug.
2. Thread a ¾" x 1½" nipple, a 90° street
elbow, or a Honeywell ange onto the gas
valve and pipe through the slot in the left
jacket panel (Figure 5-a). In Canada, close
nipples and street ells are not approved for
use as gas piping.
3. Pipe through the left jacket panel, and
complete drip leg as shown (Figure 5-a).
