Draft hood installation
Secure the draft hood to the outlet at the top of the boiler
with sheet metal screws. The bottom of the draft hood
or "skirt" must have the clearance dimension above the
jacket top panel as indicated on the draft hood.
Spill switch installation
Fasten spill switch to draft hood as shown on page 1.
Connect wires as shown on wiring diagram label located
inside boiler door.
Damper installation
If damper will be installed, see Control Supplement for
information.
Breeching erection
(Also refer to chimney or vent requirements, Page 4)
Connect from draft hood or damper outlet to chimney
or vent with same size as breeching. Where possible,
vertical venting to the outside from the draft hood or
damper outlet will offer best performance. Where hori-
zontal breeching is used, slope upward at least ¼ inch
per lineal foot toward the chimney or vent and support
with hangers to prevent sagging.
Breeching must not be connected to any portion of a
mechanical draft system that can operate under posi-
tive pressure.

Do not alter draft hood. CSA design
certification becomes void. If draft hood
is altered, severe personal injury or death
will occur, resulting from flue gas spillage
or carbon monoxide emissions.
(PFG-5 ONLY)
A minimum vertical height of 3 feet of
breeching before any elbow or horizontal
breeching is recommended to reduce
chances of flue gas spillage at the draft
hood. Long horizontal breechings,
excessive numbers of elbows or tees, or
other obstructions that restrict the flow
of combustion gas should be avoided.

Wiring
For your safety, turn off the electrical
power supply at the service entrance panel
before making any electrical connections
to avoid possible electrical shock hazard.
All wiring must be installed in accordance with re-
quirements of the National Electrical Code and any
additional national, state or local code requirements
having jurisdiction. All wiring must be N.E.C. Class 1.
The boiler must be electrically grounded in accordance
with the National Electrical Code, ANSI/NFPA No. 70-
latest edition.
In Canada, all wiring must be done in accordance with
the CSA C.1 Canadian Electrical Code Part 1.
If original rollout thermal fuse element wire as supplied with
PFG-5 boiler must be replaced, type 00°C wire or
equivalent must be used. If other original wire as sup-
plied with any PFG boiler must be replaced, type 105°C
wire or equivalent must be used.
The boiler is shipped with control components com-
pletely wired except for spill switch and damper (if
provided).
A separate electrical circuit should be used for the
boiler with a fused disconnect switch (15 amp. recom-
mended).
Refer to wiring diagram label affixed to the inside of
the jacket door. Bring electrical supply through proper
opening in the jacket left end panel and into the electri-
cal junction box. Wire electrical supply, circulator and
thermostat as shown on the wiring diagram.
For boilers equipped with control systems other than
constant burner pilot, refer to separate instructions for
application data.
Install room thermostat
Install room thermostat on an inside wall. Never install
where it will be influenced by drafts, hot or cold water
pipes, lighting fixtures, television, rays of the sun or
near a fireplace.
Heat anticipator in thermostat must be set to match the
power requirements of the primary control to which it
is connected. Refer to wiring diagram on jacket door for
recommended heat anticipator setting with standard
equipment. Wire the thermostat as shown.
