Page 19: Vent Pipe Preparation And Joining
Vent Pipe Preparation and Joining Most failures in vent systems result from improper preparation and joining of pipe and fittings. The guidelines below must be followed when installing the venting system. If you have any question about the application or installation of the venting system, contact the vent pipe manufacturer, supplier, or your plumbing professional. - Page 20 Vent Pipe Preparation and Joining continued- d) Cementing must be done quickly to avoid over-drying before joining. Apply one coat to the outside end of the pipe at a width slightly greater than the depth of the socket. ii) Apply a coat around the inside of the fitting socket. iii) Apply a second coat around the end of the pipe.

Page 21: Combustion Air Supply
Combustion Air Supply WARNING Liquefied petroleum gases/propane gas are heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. - Page 22 Installation (Combustion Air Supply) continued- All Air From Inside the Building: The confined space must be provided with two permanent openings communicating directly with an additional room(s) of sufficient volume so that the combined volume of all spaces meets the criteria for an unconfined space.
