The heater is design certified by CSA International for installation on combustible flooring. For installation on car- peting, the heater must be mounted on a metal or wood panel that extends at least three (3) inches beyond the base of the heater. If the heater is installed in a closet or alcove, the entire floor shall be covered by the panel.
On an indoor installation, the exhaust discharges into a vent pipe. Orient the heater so that the vent pipe does not interfere with adjustment of the operating controls. The operating control panel located on top of the jacket can be rotated for convenient access to the control panel.

COMBUSTION AND VENTILATION AIR SUPPLY
For indoor installation, the heater requires air supply open- ings for ventilation and combustion. The minimum require- ments are for two (2) openings: one 12 inches from the ceiling for ventilation air and one 12 inches from the floor for combustion air, in accordance with the latest edition of the National Fuel Gas Code, ANSI Z223.1., and any local codes that may apply.
The minimum net free area in square inches shall be as follows:

INDOOR VENT INSTALLATION
Always vent the heater to the outdoors.
•Vent it horizontally or vertically using a Special Gas Vent, (see Table 5, Page 14), or
•Vent it vertically using Type “B” double wall vent con- nector pipe.
Locate the heater so as to minimize the length of horizon- tal venting and the number of vent elbows required. Horizontal vent runs must slope up 1/4” per foot from the heater to allow exhaust condensate to drain and must have a condensate drain as described in the venting installation instructions.
