H18.4.1A
5. Turn off gas and electrical supply to furnace, remove the manometer hose from the inlet pressure tap boss,
and tighten the inlet pressure tap screw using the 3/32” Allen wrench. (Clockwise, 7 in-lb minimum).
6. Turn on the gas supply and electrical power to the furnace.
7. Using a leak detection solution, check for leaks at pressure boss screw. Bubbles forming indicate a leak.
SHUT OFF GAS AND FIX ALL LEAKS IMMEDIATELY!
8. Turn gas back on and test inlet pressure boss with leak detector.
If problems were encountered with obtaining enough pressure,
fi
rst examine the gas piping system to ensure
that it is correctly sized. Pipe sizing is speci
fi
ed in CAN/CSA-B-149.1 & 2, and in NFPA 54 / ANSI Z223.1. Be
sure to check for restrictions, partially closed valves, etc.
In some circumstances, high inlet pressure can be remedied with the use of an in line appliance regulator. If
an in line appliance regulator is used, ensure that it has the capacity to adequately handle the gas volume
required by the furnace and any other appliances receiving gas from the header serving the furnace.
When the installation is completed to the
“Start-up & Setup”
stage, test the gas manifold pressure by following
these steps:
WHITE-RODGERS 36J24-214 SINGLE STAGE GAS VALVE
1. Turn off the gas and electrical supply before proceeding.
2. Back outlet pressure test screw (outlet pressure boss, see
fi
g. 28 & 29) counterclockwise out one more
turn maximum, with a 3/32” Allen wrench. Attach a hose and calibrated U-tube or digital manometer to the
outlet pressure boss. Hose should overlap boss 3/8”. The manometer must have a scale range of at least
0” to 15” of water column.
3. Turn on the gas supply and electrical power to the furnace and energize main solenoid by connecting R to
W on the integrated control board.
4.
Remove regulator adjust cover screw from the outlet pressure regulator adjust tower (
fi
g.28) and turn
the plastic regulator adjustment screw clockwise to increase manifold pressure or counterclockwise to
reduce manifold pressure. Manifold pressure should be set to 3.5” w.c for natural gas, 10.0” w.c. for LP
gas. Always adjust regulator according to original equipment manufacturer’s speci
fi
cations listed on the
appliance rating plate.
When the correct pressure has been established, securely replace the regulator cover screw.
5. Turn off the gas and electrical supply to the furnace.
