GAS PIPE TESTING
The appliance and its shutoff valves must be disconnected from the gas supply piping system
during any pressure testing where the pressure exceeds 1/2 PSIG (3.45 kpa).
Always check for gas leaks with a soap and water solution, after completing the required
pressure test.
NEVER US AN OPEN FLAME FOR LEAK TESTING
When using copper or flex connectors use only fittings approved for gas connections. The gas
control inlet is 3/8" NPT, therefore the 1/2" rigid gas line must be reduced to 3/8" NPT. A
typical gas line installation layout for rigid pipe is shown on the previous page.
VENTING (COAXIAL 6" AIR INTAKE & 4" EXHAUST)
Kits are available for venting either through the sidewall or vertically through the roof .
SIDEWALL VENTING
THIS APPLIANCE MUST BE INSTALLED WITH A MINIMUM VERTICAL LENGTH
OF 18" TO THE FIRST 90 DEGREE ELBOW. WITH THIS MINIMUM VERTICAL RISE,
HORIZONTAL RUNS OF UP TO 18" ARE PERMITTED TO REACH THE OUTSIDE
VENT TERMINATION.
FOLLOW THE VENTING INSTRUCTIONS ON THE FOLLOWING PAGES PRECISELY
BEFORE BEGINNING THE INSTALLATION, TAKING CARE TO ENSURE AN
APPROPRIATE OUTSIDE LOCATION FOR THE VENT TERMINATION CAN BE
ACCOMMODATED.
ALSO, TAKE CARE TO REVIEW THE DIAGRAM ON THE FOLLOWING PAGE
WHICH OUTLINES LOCATION LIMITATIONS GOVERNED BY NATIONAL CODE.
SINCE THE DIRECT VENT IS AN UNPRESSURIZED SYSTEM, IT WILL BE
SENSITIVE TO LOCAL CONDITIONS SUCH AS ELEVATION, WIND
CONDITIONS, VENT LOCATION AND FUEL TYPE UTILIZED. THIS WILL
AFFECT THE OVERALL APPEARANCE OF THE GAS FLAME.
