Gas Supply
The burner system requires gas supplied at the
correct pressure. If the gas pressure supplied to
the unit is either too high or too low, the burner
system will work improperly or not at all. Confirm
the gas pressure meets the requirements shown
on the nameplate of the unit.
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 significantly at these
times, which will interfere with the proper
operation of the burner.
WARNING
Only a qualified and
experienced Combustion
Service Technician should
install and adjust any
gas components.
CAUTION
The gas supply must match
the specific gas
requirements shown on
the nameplate.
Follow the procedure below for the type of gas
that is being used—natural/manufactured gas, or
liquefied petroleum gas.
For Natural or Manufactured Gas:
WARNING
Turn the power OFF at
the main disconnect
switch before performing
this procedure.
1. Turn the power OFF at the main discon-
nect switch.
WARNING
Do not adjust or test gas
components unless you are
qualified to do so.
2. Connect a U-tube or other water column
manometer upstream of the supplied pres-
sure regulator, and measure the static gas
pressure.
If the pressure is:
• Less than 5" (130 mm):
Burner will not work reliably. Correct
the gas pressure before proceeding.
• 5" - 11" (130 - 280 mm):
Proper operating range.
• More than 11" (280 mm):
This is a high pressure gas supply. In-
stallation of an additional regulator is
necessary:
a) The additional regulator must be
mounted horizontally.
b) Connect the manometer between
the two regulators.
c) Measure the incoming gas pressure
to the supplied regulator to make
sure it is now in the proper range.
For information on the maximum operat-
ing inlet pressure within this manual, pro-
ceed to the APPENDIX, Technical
Specifications section.
