Check Gas Pressure
It is important to check the available gas
pressure to the unit during periods of peak
demand by other gas-heated equipment in the
laundry room or elsewhere at the facility. Gas
pressure to the unit may be reduced signicantly
at these times, which will interfere with the proper
operation of the burner.
For more information on checking the gas
pressure, refer to Gas Connection Checkout
on page 2-20.
