INSTALLATION

5. Uniformly apply liberal coat of primer to inside socket surface of fi tting and
male end of pipe to depth of fi tting socket.
6. Promptly apply solvent cement to end of pipe and inside socket surface
of fi tting. Cement should be applied lightly—but uniformly—to inside of
socket. Take care to keep excess cement out of socket. Apply second coat
to pipe end. Time is critical at this stage. Do not allow primer to dry before
applying cement.
7. Immediately after applying last coat of cement to pipe, while inside socket
surface and end of pipe are wet with cement, insert end of pipe into
socket, turn pipe 1/4 turn to distribute cement evenly, continue to insert
pipe until it bottoms out.
NOTE: Assembly should be completed within 20 seconds after last
application of cement. Do not use hammer to insert pipe.
8. After assembly, wipe excess cement from pipe at end of fi tting socket. A
properly made joint will show a bead around its entire perimeter. Any gaps may
indicate a defective assembly due to insuffi
cient cement.
9. Handle joints carefully until completely set.
Install Intake Muffl er
To install intake muffl er, cement joints as indicated in previous section. For
best noise attenuation, the muffl er should be installed as close to the boiler
as possible, and can be horizontal or vertical in orientation.
Preparing to Install Exhaust Vent Piping
A Fulton Pulse boiler should not be connected to a common venting system with
other types of gas appliances. Adhere to the following when preparing to install
vent piping:
1. The boiler is equipped with an exhaust vent connection located at the
rear of the boiler. For models PHW300 up through the PHW1400, the
connection is 4” NPT threaded female. Model PHW2000, the connection is
6” NPT threaded female.
2. The exhaust line must be sloped down toward the boiler with a pitch of
at least 1/4” per foot. Failure to do so can result in a condensate pocket
which can result in an inoperative boiler. There must be no low spots in
the exhaust pipe, as this can also result in a condensate pocket. A high spot
is acceptable, provided the pitch from the high spot is maintained back to
the boiler or to the outside point of the exhaust. In supporting piping, or
routing it through a rafter or wall, always use vibration eliminating hangers
around the piping to prevent vibration transmission. Always avoid rigid
connections between piping and structural members of the building.
3. All alternative individual venting arrangements must result in an exhaust
pressure drop not to exceed 2.5” w.c. (Consult factory for assistance.)
