including the National Fuel Gas Code ANSI Z223.1/NFPA No. 54. In Canada;
Refer to the CSA B149.1 Gas Installation Code. If the flue pipe exceeds 10
feet in length or contains more than two elbows, the natural draft may be
eliminated and the burner will not ignite. DO NOT install a movable flue
pipe damper.
4. If the unit is being installed in an enclosed room, provide adequate air for
combustion by installing openings to the room near the ceiling for ventilation
and near the floor for burner combustion. These openings should be sized
using one square inch for each 1000 BTU per inch of the machine.
Example: A heater module with a 400,000 BTU input requires openings
of 400 square inch or approximately 3 feet x 1 foot.
5. If the building in which the unit is being installed seems unusually tightly
constructed, it is recommended that air intakes extending to the outside of
the building be employed to supply combustion air. End the intakes outside
the building with a downward opening to protect these intakes from snow
and/or rain. Include a mesh screen no smaller than 1/4" over the opening.
WATER SUPPLY:
1. Using the quick connect at the inlet of the unit, connect the water supply
to the unit. For best results, the input to the unit should be 3-6 GPM.
NOTE: Incoming water pressure must not exceed 3500 PSI.
2. Connect the discharge hose provided to the outlet of the unit.
3. Connect gun/wand/lance assembly to the discharge hose.
4. Make sure all connections are secured before start-up.
HIGH PRESSURE CONNECTION:
Connect the high pressure discharge hose by connecting one end to the
heater module and the other end to the gun assembly. Make certain the
quick connects are securely locked together.
