Before Installing
- Make sure that there is enough space for
installing Water and gas line.
Verify vent/air termination is located as required.
- All models need for propane Conversion which
requires a separate gas conversion manual.
Install Water Piping
- Boiler loop piping must be sized to the minimums
listed in the Boiler manual. Using smaller piping
will cause performance problems.
Install Vent & Air Piping
- Slide the air inlet pipe and vent pipe into the
Boiler pipe connector.
- Make sure the terminations are placed as
required in the manual and that air intakes are at
least 12 inches above normal snow line.
- Refer to the material check list in this guide for a
list of items needed.
Install Condensate Piping / Tubing &
Components
- Fill out the material check list in this guide to
ensure you have the tubing or PVC pipe and all
components needed for the condensate piping.
- Connect internal components that are supplied
with the Boiler.
Install Gas Piping
- Install a union and shutoff valve.
Wire the Boiler
- Connect power wiring and control wiring per
boiler manual wiring diagram.(Section 4.19)
Start up, Adjust & Test

chemistry.
9.2 Final Check Lists
Final check : Installation Conditions.
• Is the Boiler properly mounted on the wall?
• Is there space for a drain which is close to the
Boiler?
• Are there any combustible materials near the
Boiler and vent pipe?
• Is the air supply sufcient for proper operation of
the Boiler?
• Are the proper service clearances maintained?
• Is the distance between the Boiler and point of
vent termination minimized?
• Is the proper distance from windows, doors, and
other intake vents maintained?
Final check : Gas pipe installation
• Is the gas supply line equipped with a manual
shut off valve?
• Is the gas supply line a minimum of 3/4˝ inner
diameter?
• Is the gas supply line length and diameter
adequate to deliver the required BTU’s?
• Has the gas supply line pressure been
measured?
• Does the supply gas type match the type
indicated on the boiler rating plate?
Final check: Air/Vent pipe installation
• Has the Boiler been vented with 3˝ or 2” PVC,
CPVC, Polypropylene or BH Special
Gas Vent (S636 PVC, CPVC) for Category IV
appliances in accordance with this manual and/or
your local code?
• Is the vent termination at least 12˝ above the
exterior grade?
• Is the total vent length within the maximum vent
length restriction?
• Have you checked the air/vent piping for leaks?
• Have you properly supported the vent
termination?
• Are all vent runs properly supported?
• Is the vent sloped upward toward the vent
termination at a rate of 1/4˝ per foot (2% grade)?
Final check : Condensate drain installation
• Have you installed a condensate drain line from
the Boiler to a drain or laundry tub?
Final check : Setting the DIP switches
• Are all DIP switches correctly set on the main
board?
