Figure 19 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 de- pend on the pitch of the roof. There MUST BE a 1-inch (25mm) clearance from the vertical 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 collar and the vertical pipe.

•Slide the termination cap over the end of the flue pipe and rotate the pipe clockwise 1/4 turn.

1.4 CONNECTING THE GAS SUPPLY

The gas is introduced to the appliance on the left hand side. See Figure 20.

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 ex- terior side of the unit. Figure 21 shows the fan, switches, and fan wiring diagram.
