Connecting The Gas Supply; Fan - Heat-N-Glo SL-550TRS-AUC Installation And Operation Instructions Manual

For Vertical Terminations - To locate the flue
and install the flue sections:
• Locate and mark the flue centerpoint on the un-
derside of the roof, and drive a nail through the
centerpoint.
• Make the outline of the roof hole around the
centerpoint 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.

1.3 CONNECTING THE GAS SUPPLY

The gas is introduced to the appliance on the left
hand side. See Figure 25. After the gas pipe in-
stallation is complete, check carefully all gas con-
nections 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.

1.4 FAN

These heaters have a factory installed Fan, Elec-
trical Junction Box, Variable Speed Rheostat Con-
trol Switch and Temperature Sensor Switch for
the fan. These components are located behind
the lower grille.
Use of the fan requires that the Junction Box (fac-
tory installed) be connected to 240 VAC service
before permanently enclosing the heater. The
access hole for connecting the service wires is
found on the right exterior side of the unit. Figure
26 shows the fan, switches, and fan wiring dia-
gram.
