Final checks before starting the boiler

Read the FTXL Service Manual to familiarize yourself with
SMART SYSTEM control module operation. Read this
manual, page 60 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 10, pages 57
and 58 have been completed.

Verify electrical connections are correct and securely
attached.

Inspect vent piping and air piping for signs of deterioration
from corrosion, physical damage or sagging. Verify air
piping and vent piping are intact and correctly installed per
this manual.
Start the boiler
1. Read and follow the Operating instructions in FIG. 10-2,
page 60.
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 (93°C)?
3. Is thermostat set below room temperature?
4. Is gas turned on at meter or boiler?
5. Is incoming gas pressure less than 4 inches w.c. (.99 kPa)?
If none of the above corrects the problem, refer to the
Troubleshooting Section of the FTXL 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
57 and 58 (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 vent piping and air piping
1. Check for gastight seal at every connection, seam of air
piping, and vent piping.
Venting system must be sealed gastight
to prevent fl ue gas spillage and carbon
monoxide emissions, which will result in
severe personal injury or death.

Check gas piping
1. Check around the boiler for gas odor following the
procedure on page 48 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 fi eld 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 fl ame and combustion
1. Turn the main power off to the boiler by placing the
“On/Off” switch in the OFF position.
2. Remove the brass plug from the combustion
measurement port inside the fl ue collector. 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.

WARNING
FTXL boilers are typically shipped ready
to fi re 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 a LP venturi
or by making a gas valve adjustment (see
pages 14 and 15). In order to operate on
LP gas, a LP venturi MUST BE installed or
a gas valve adjustment MUST BE made.
Failure to comply could result in severe
personal injury, death, or substantial
property damage.
