BOILER FLUE PASSAGE
Burner And Pilot Flame
Manufacture recommends flue passages, burner
Manufacture recommends flue passages, burner
adjustments and operation of boiler controls be checked
once a year by a service technician.
To clean flue passages:
To clean flue passages:
A. Remove burners and pilot(s) from boiler.
B. Remove clean-cut cover panel on draft hood to
B. Remove clean-cut cover panel on draft hood to
expose flue passages.
See Figure 13 page 16.
C. Clean flue passageways between sections with
flexible handle wire brush. Remove all dirt from
bottom of boiler and reassemble all parts.
D. Verify pilot connection(s), adjustment of pilot(s)
and burner flames after reassembly.

High Limit Control
While boiler is operating, set high limit control below boiler
water temperature and main burners should shut off. Return
control to normal setting. Main burners should restart.
WARNING
Burn and scald hazard. Discharge of water, vapor
and steam may scald. Failure to follow these
instructions could result in death or serious injury.
!
Pressure Relief Valve
1.
Pressure relief valve on boiler is required.
2.
Run a pipe from pressure relief valve outlet to
appropriate open drain.
3.
Pipe must be of same size as outlet on valve and open
end must not be threaded.
4.
Run drain in area not subject to freezing. Failure to
do so may cause water damage or injury should valve
release.
5.
If valve discharge occurs, or valve fails to open as
described above, contact service technician to replace
relief valve and inspect heating system to determine
cause, as this may indicate equipment malfunction.
6.
Follow valve manufacture instructions for testing and
maintenance.
Burner And Pilot Flame
1.
Manufacture recommends visual check of burners and
pilot flame monthly during heating season by owner
and once year by service technician.
See Figure 39.
2.
Look for deterioration from corrosion of burners, pilot
burners and boiler base frame.
3.
Clean boiler base interior and exterior.
Verify Burner Input
Check boiler for proper Btu input rate. Do not exceed Input rate
stamped on nameplate of boiler located on end jacket panel.
Verify primary air supply to main burners is properly
adjusted for complete combustion.
If boiler is shut down for service, gas and electric must be
off for 5 minutes before relighting.
Verify boiler for proper Btu Input proceed as follows:
1.
With main burners operating, measure gas Input to
boiler by reading the gas meter.
2.
Verify all other appliances connected to same meter are
shut off.
3.
Rate of gas flow (cu. ft. per hour) multiplied by Btu
value of gas should match Btu input shown on boiler
nameplate.
4.
If it is not within +/- 2%, adjust Pressure Regulator
to obtain desired flow. Adjustment stem can be found
cap regulator top. Adjustment screw is plastic and
may require slightly greater turning force than metal
threads.
5.
Turn clockwise to increase input and counterclockwise
to decrease input rate.
6.
Replace Regulator Cap.
CHECKING AND ADJUSTING
Figure 39 - Pilot and Flame
Venting System
1.
Check chimney for correct size, proper construction,
clean and in good condition to ensure proper
combustion.
2.
You must provide enough fresh air for combustion.
3.
If your building is of tight construction, it may be necessary to
add fresh air duct to provide oxygen. See Chart 3, page 8.
4.
Monthly during heating season check that sections of
vent pipe are secure at all joints and fittings. There
should be at least two (2) sheet metal screws per joint.
5.
Check that vent pipe slopes at least 1/4” per foot up
from boiler to chimney.
6.
Vent pipe should be securely fastened to prevent
sagging.
7.
Check vent Pipe for any deterioration from corrosion or
any other sources.
8.
Refer to Venting and Combustion Air instructions in this
manual.
WARNING
Asphyxiation hazard. Improper installation could
result in death or serious injury. Failure to follow
these instructions could result in death or serious
injury.
