1.1 INTRODUCTION
This model is designed to operate with all combustion
air being siphoned from the outside of the building
and all exhaust gases expelled to the outside of the
building.
WARNING: THIS UNIT IS NOT FOR USE WITH
SOLID FUEL.
These units
MUST
use the fl ue termination described
in the fl ueing section of the manual.
The control system for this model is an electronic ig-
nition type. It consists of a gas control valve/variable
regulator, a pilot/sensor/electrode and an ON/OFF
switch. The controls are located behind the access
door. Rotate the door down to open. See Figure 1.
Minimum inlet gas supply pressure for purpose of
input adjustment is 1.13 kPa for natural gas and 2.75
kPa for propane. Manifold (outlet) pressures should
be set at .8 kPa for natural gas models and 2.36 kPa
for propane models.
