For Vertical Terminations - To locate the fl ue and
install the fl ue sections:
• Locate and mark the fl ue centerpoint 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 25 mm
clearance from the vertical fl ue pipe to combustible
materials.
• Mark the roof hole accordingly.
• Cover the opening of the installed fl ue 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 fl ue 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 fl ue system:
• Attach a fl ashing to the roof using nails, and use a
non-hardening mastic around the edges of the fl ash-
ing base where it meets the roof.
• Attach a storm collar over the fl ashing 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 fl ue
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 40). After the gas pipe installation
is complete, check carefully 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. See Table 1 for pressure requirements.
NOTE: THE GAS SUPPLY LINE SHOULD BE
PURGED OF ANY TRAPPED AIR PRIOR TO THE
FIRST FIRING OF THE UNIT.
