Start-up
Check vent piping and air piping
1. Check for gastight seal at every connection, seam, 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 11 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 fitting from the flue collector.
Note:
Combustion measurements will be made at this point.
3. Insert the probe from a combustion analyzer into the
hole left by the removal of the fitting.
4. Turn the main power on to the boiler by placing the “On/
Off” switch in the ON position.
5. Navigate to the Setup Screen from the Home Screen
by pressing the SETUP button along the left side of the
screen. Enter the installer password.
6. Select the Service Maintenance Screen. The tabs will
scroll (up and down) to reveal more options.
On the Service Maintenance Screen place heater into
Service Mode by selecting the START button, then
selecting
Set Gas Valve 1 - High

8. Once the heater analysis is complete, test the safety shutoff
device by turning the manual shutoff valve to the OFF
position and ensuring the heater shuts down and registers
an alarm. Open the manual shutoff valve and reset the
control.
9. Turn the main power off to the boiler and replace the
fitting into the flue pipe connection.
10. Ensure the boiler is placed back into normal operation.
You must replace the fitting to prevent flue
gas spillage into the room. Failure to comply
could result in severe personal injury, death,
or substantial property damage.
⚠
WARNING
7. Once the boiler has modulated up to rate, measure the
combustion. The values should be in the range listed in
Table 3B (this page). 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 Outdoor Crest Service Manual for possible causes
and corrective actions.
