B.INSTALLATION
1.Attach combustion air intake piping to supplied Fernco 2" coupling on mixer. Attach vent piping to furnished 2" CPVC vent tee on draft inducer outlet.
NOTE: All pipe joints are to be water tight.
2.Working from the boiler to the outside, cut pipe to required length(s).
3.Deburr inside and outside of pipe.
4.Chamfer outside edge of pipe for better distribution of primer and cement.
5.Clean and dry all surfaces to be joined.
6.Check dry fit of pipe and mark insertion depth on pipe.
NOTE: It is recommended that all pipes be cut, prepared, and
7.After pipes have been cut and
8.While cement is still wet, insert pipe into socket with a’/a turn twist. Be sure pipe is fully inserted into fitting socket.
9.Wipe excess cement from joint. A continuous bead of cement will be visible around perimeter of a properly made joint.
10.Handle pipe joint carefully until cement sets.
11.Support combustion air and vent piping a minimum of every 5 feet using
12.Slope combustion air and vent pipes toward boiler a minimum of 1/4" per linear foot with no sags between hangers.
13.Use appropriate methods to seal openings where vent and combustion air pipes pass through roof or side wall.
GAS SUPPLY PIPING
A. CHECK GAS SUPPLY
The gas pipe to your boiler must be the correct size for the length of run and for the total BTU per hour input of all gas utilization equipment connected to it. See Table 3 for the proper size. Be sure your gas line complies with local codes and gas company requirements.
The boiler and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ‘/z psig (3.5kpa).
The boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ‘/z psig (3.50ka).
