Installation & Operation Manual
Final checks before starting the boiler
Read the Power-fin Service Manual to familiarize yourself
with SMART TOUCH control module operation. Read
this manual, page 46 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 9, pages 43
and 44 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. 9-2,
page 46.
If boiler does not start correctly
1. Check for loose connections, blown fuse or service switch
off?
2. Is external limit control (if used) open? Is boiler water
temperature above 200°F (93°C)?
3. Is the boiler receiving a call for heat?
4. Is gas turned on at meter and 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 Power-fin 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 43 and 44 (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 flue 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 35 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.
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
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.
4. Navigate to the Service Maintenance Screen from the
Home Screen by pressing the SETUP button, enter the
installer password, and then using the scrolling menu
feature on the left side, scroll down to the SERVICE
MAINTENANCE button.
5. On the Service Maintenance Screen place heater into
Service Mode by selecting the START button, then
selecting
Set Gas Valve - High
.
6. Insert the probe from a combustion analyzer into the
hole left by the removal of the flue temperature sensor.
7. Once the heat exchanger has modulated up to rate,
measure the combustion. The values should be in the
range listed in
Table 9A
of the Power-fin Service Manual.
CO levels should be less than 200 ppm for a properly
installed unit. If the combustion is not within range
reference the
Troubleshooting
Section in the Power-
fin Service Manual for possible causes and corrective
actions.
8. Once the heater analysis is complete, test the safety
shutoff device by turning the manual shutoff valve to the
OFF position and ensuring that the heater shuts down
and registers an alarm. Open the manual shutoff valve
and reset the control.
