1.4 CONNECTING THE GAS SUPPLY
The gas is introduced to the appliance on the left hand
side. See Figure 18.
After the gas pipe installation is complete, check care-
fully all gas connections for leaks with a soap solution.
DO NOT USE AN OPEN FLAME.
NOTE:
THE GAS SUPPLY LINE SHOULD BE
PURGED OF ANY TRAPPED AIR PRIOR TO THE
FIRST FIRING OF THE UNIT.
1.5 FAN
These heaters have a factory installed Fan, Electrical
Junction Boxes, variable speed Rheostat Control Switch
and Temperature Sensor Switch for the fan. These com-
ponents are located behind the lower grille.
Use of the fan requires that the Junction Box (factory
installed) be connected to 240 VAC service before per-
manently enclosing the heater. The access hole for
connecting the service wires is found on the lower front
exterior side of the unit. Figure 19 shows the fan,
switches, and fan wiring diagram.
Figure 17 Round Termination Caps
For Vertical Terminations -
To locate the flue and
install the flue sections:
Locate and mark the flue center point on the un-
derside of the roof, and drive a nail through the
center point.
Make the outline of the roof hole around the cen-
ter point nail.
The size of the roof hole framing dimensions
depend on the pitch of the roof. There
MUST
BE
a 1-inch (25mm) clearance from the verti-
cal flue pipe to combustible materials.
Mark the roof hole accordingly.
Cover the opening of the installed flue pipes.
Cut and frame the roof hole.
Use framing lumber the same size as the roof
rafters and install the frame securely. Flashing
anchored to the frame must withstand heavy
winds.
Continue to install concentric flue sections up
through the roof hole and up past the roof line
until you reach the appropriate distance above
the roof.
CAUTION: FOLLOW THE REQUIREMENTS
OF THE AGA GAS INSTALLATION CODE FOR
MINIMUM HEIGHT REQUIREMENTS ABOVE
THE ROOF.
To seal the roof hole, and to divert rain and snow
from the flue system:
Attach a flashing to the roof using nails, and
use a non-hardening mastic around the edges
of the flashing base where it meets the roof.
Attach a storm collar over the flashing joint to
form a water-tight seal. Place non-hardening
mastic around the joint, between the storm col-
lar and the vertical pipe.
Slide the termination cap over the end of the
flue pipe and rotate the pipe clockwise 1/4 turn.
