1.4 CONNECTING THE GAS SUPPLY
The gas is introduced to the appliance on the left hand
side. See Figure 24.
After the gas pipe installation is complete, check care-
fully all gas connections for leaks with a commercially-
available, non-corrosive leak check solution. Be sure
to rinse off all leak check solution following testing.
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.
FIGURE 23. Termination Cap
For Vertical Terminations -
To locate the flue and
install the flue sections:
•
Locate and mark the flue center point on the under-
side of the roof, and drive a nail through the center
point.
•
Make the outline of the roof hole around the center
point nail.
•
The size of the roof hole framing dimensions depend
on the pitch of the roof. There
MUST BE
a 1-inch (25
mm) clearance from the vertical flue pipe to combus-
tible 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 flash-
ing 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.
