8 Installing Vent Pipe

A. Assembly of Vent Sections

WARNING

Do not mix pipe, fittings or joining methods from different manufacturers.

WARNING

Fire Risk

Exhaust Fumes Risk

Impaired Performance of Appliance

• Overlap pipe slip sections at least 1-1/2 inches.

• Use pilot holes for screws.

• Screws must not exceed one inch long.

• Pipe may separate if not properly joined.

Attaching Vent to the Firebox Assembly

To attach the first pipe section to the collars, slide the male end of the inner vent of the pipe section over the inner collar on the firebox assembly. At the same time, slide the outer flue over the outer collar on the appliance. Push the pipe section into the appliance collar until all the lances (see Figure 8.2) have snapped in place. Tug slightly on the sec- tion to confirm it has completely locked into place.

Make sure that the fiberglass rope ring supplied in the manual bag seals between the first vent component and the outer appliance wrap (see Figure 8.1)

Commercial, Multi-family (Multi-level exceeding two stories), & High-Rise Applications

For Installation into Commercial, multi-family (multi-level ex- ceeding two stories) or high-rise applications: All pipe joints must be sealed with silicone with a minimum of 300ºF contin- uous exposure rating, including the slip section that connects directly to the horizontal termination cap.

•Apply a bead of silicone sealant inside the female outer pipe joint prior to joining sections. See Figure 8.2

•Only outer pipes are sealed. Do not seal the inner flue. All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed in this manner, unless otherwise stated.

Note: The end of the pipe sections with the lances/tabs on it will face toward the appliance.

WARNING

Fire Risk Explosion Risk

If slip section seals are broken during the removal of the termination cap, gas will leak and a fire or explosion may occur.

Do not break silicone seals on slip sections.

Assembling Pipe Sections

Insert the inner flue of section A into the flared inner flue of section B.

Start the outer flue of section A over the outer flue of section B (see Figure 8.3). Note: The end of the pipe sections with the lances/tabs on it will face towards the appliance. Once both inner and outer flues are started, press section A onto section B firmly until all lances have snapped into place. Check to make sure they have snapped together (see Fig- ure 8.4) and the seams are not aligned (see Figure 8.5). Tug slightly on section A to confirm it has completely locked into place. It is acceptable to use screws no longer than 1 inch to hold outer pipe sections together. If predrilling holes, do NOT penetrate inner pipe.

For 90° and 45° elbows that are changing the vent direction from horizontal to vertical, one screw minimum should be put in the outer flue at the horizontal elbow joint to prevent the elbow from rotating. Use screws no longer than 1 inch. If predrilling screw holes, do NOT penetrate inner pipe.
