INSTALLATION REQUIREMENTS
Gas piping must conform to the current National Fuel
Gas Code, ANSI Z223.1.
Always consult with the local code official for additional
local codes applicable in your area.
IMPORTANT: Always check for gas leaks with a soap
and water solution or gas leak detector. Never use open
flame for leak testing.
NOTE: To properly check gas pressure, both inlet
and manifold pressures should be checked using the
valve pressure ports on the control valve.
The manifold pressure is controlled by a regulator built
into the gas control, and should be checked at the
pressure test point.
1) Make sure the valve is in the “ OFF” position.
2) Loosen the “IN” and/or “OUT” pressure tap(s),
turning counterclockwise with a 1/8” wide flat
screwdriver.
3) Attach manometer to “IN” and/or “OUT” pressure
tap(s) using a 5/16” ID hose.
4) Light the pilot and turn the valve to the “ON”
position.
5) The pressure check should be carried out with the unit
Burning and the setting should be within the limits
specified on the safety label.
6) When finished reading the manometer, turn off the gas
Valve. Disconnect the hose and tighten the screw
(clockwise) with a 1/8” flat screwdriver.
Note: screw
should be snug. But do not over tighten

HEARTH MATERIALS
A Hearth is not mandatory with the ASC-42 series
fireplace, but is recommended for aesthetics and for
added safety .
Non-combustible materials such as Tile, Brick, Rock, and
Slate are recommended. The appliance should not be
installed over existing carpeting.
In constructing a hearth, hearth material thickness must
be taken into consideration. Avoid using any material that
will block the front of the valve access door at the bottom
of the fireplace.
NOTE: If the appliance is to be installed on carpeting,
vinyl tiling, or any other combustible material other
than wood flooring, the appliance must be installed on
a metal or wood panel extending the full width and
depth of the appliance.
