Final checks before starting the boiler
Read the Outdoor Knight Boiler Service Manual to
familiarize yourself with SMART SYSTEM control
module operation. Read this manual, page 36 for proper
steps to start boiler.
Verify the boiler and system are full of water and all
system components are correctly set for operation.
Verify the preparation procedures of Section 7, pages 33
and 34 have been completed.
Fill the vent condensate trap with water (removing the
retaining screw in order to remove the 2 inch PVC cap
with the switch located at the top of the trap). Replace
the cap. Press the cap onto the trap until the cap makes
contact with the drain. Replace the retaining screw.
Verify electrical connections are correct and securely
attached.
Verify air opening and vent opening are free of
obstruction.
Start the boiler
1. Read and follow the Operating instructions in FIG. 7-2,
page 36.
If boiler does not start correctly
1. Check for loose connections, blown fuse or service switch
off?
2. Is boiler water temperature above 200°F?
3. Is thermostat set below the controlling sensor
temperature?
4. Is gas turned on at meter or boiler?
5. Is incoming gas pressure less than 4 inches w.c.?
If none of the above corrects the problem, refer to the
Troubleshooting Section of the Outdoor Knight Boiler
Service Manual.
Check system and boiler
Check water piping
1. Check system piping for leaks. If found, shut down
the boiler and repair immediately. (See WARNINGS
on pages 33 and 34 (startup) regarding failure to repair
leaks.)
2. Vent any remaining air from the system using manual
vents. Air in the system will interfere with circulation
and cause heat distribution problems and noise.
Check gas piping
1. Check around the boiler for gas odor following the
procedure on page 24 of this manual (connecting gas supply
piping).
If you discover evidence of any gas leak,
shut down the boiler at once. Find the
leak source with a bubble test and repair
immediately. Do not start the boiler again
until corrected. Failure to comply could
result in severe personal injury, death, or
substantial property damage.
Propane boilers – verify conversion
1. Verify propane conversion has been completed per the
Propane Conversion instructions.
DO NOT adjust gas valve outlet pressure.
The gas valve is factory-set for the correct
outlet pressure. This setting is suitable
for natural gas and propane, requiring
no field adjustment. Attempting to alter
the gas valve outlet pressure could result
in damage to the valve, causing potential
severe personal injury, death, or substantial
property damage.
Check flame and combustion
1. Turn the main power off to the boiler by placing the “On/
Off” switch in the OFF position.
2. Remove the flue temperature sensor from the flue pipe
connection. NOTE: Combustion measurements will be
made at this point.
3. Turn the main power on to the boiler by placing the “On/
Off” switch in the ON position.

ƽ WARNING
Outdoor boilers are typically shipped ready
to fire on natural gas. Check boiler rating
plate to determine which fuel the boiler is set
for. If set to natural gas, it may be converted
to LP by installing an orifice (see page 11).
In order to operate on LP gas, an orifice
MUST BE installed. Failure to comply could
result in severe personal injury, death, or
substantial property damage.
