2)Set the gas appliance in its desired location. Drop a plumb bob down from the ceiling to the position of the appliance fl ue exit, and mark the location
where the vent will penetrate the ceiling. Drill a small hole at this point. Next, drop a plumbbobfromtheroofto
the hole previously drilled in the ceiling, and mark the spot where the vent
will penetrate the roof.
3)A Firestop spacer must be installed in the fl oor or ceiling of every level. To install the Firestop spacer in a fl at ceiling or wall, cut a 10 inch square hole. Frame the hole as shown in Diagram 2 and install the fi re- stop.

Diagram 3: The upper half of the fl ashing is installed under the roofi ng material and not nailed down until the chimney is installed. This allows for small adjustments.
6)Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3 feet, to avoidexcessivestressontheelbows, and possible separation. Wall straps are available for this purpose.
Galvanizedpipeisdesirableabovetheroofline duetoitshighercorrosionresistance.Continue to add pipe sections through the flashing until the height of the vent cap meets the minimum heightrequirementsspecifiedinDia.4 or local codes. Note that for steep roof pitches, the vertical height must be increased. A poor draft, or down drafting can result from high wind conditions near big trees or adjoining roof lines, in these cases, increasing the vent height may solve the problem.
7)Ensure vent is vertical and secure the base of the fl ashing to the roof with roofi ng rails, slide storm collar over the pipe section and seal with a mastic.
GAS LINE
INSTALLATION
The gas line is brought through the right side of the appliance. The gas valve is situated on the right hand side of the unit and the gas inlet is on the right hand side of the valve.
The gas line connection may be made of rigid pipe, copper pipe or an approved fl ex connec- tor. (If you are using rigid pipe, ensure that the valve can be removed for servicing.) Since some municipalities have additional local codes it is always best to consult with your local authorities and the CAN/CGA B149 installation code.
For USA installations follow local codes and/or the current National Fuel Gas Code, ANSI Z223.1.
When using copper or fl ex connectors use only approved fi ttings. Always provide a union so that gas lines can be easily disconnected for servicing. Flare nuts for copper lines and fl ex connectors are usually considered to meet this requirement.
Important:Always check for gas leaks with a soap and water solution or gas leak detector. Do not use open flame for leak testing.
