INSTALLATION
GENERAL
1. Follow all local codes, or in the absence of local codes, follow the current edition of the Na tional Fuel
Gas Code: ANSI Z223.1/NFPA 54 in the USA or B149.1 Natural Gas and Propane Installa tion Code in
Canada.
2. All gas boilers require careful and correct installa tion to ensure safe and e fficie nt opera tion.
This manual must be followed exactly. Read the “Safety Guidelines” section.
3. The manifold gas pressure is preset at the factory. It is computer controlled and should not need
adjustment.
4. Maintain proper space for servicing. Install the unit so that it can be connected or removed easily.
5. The boiler must be installed in a loca tion where the proper amount of combus tible air will be
available to it at all times without obs tructions.
6. The electrical c onnection requires a means of disconne ction, to terminate power to the water heater.
This is necessary for servicing and safety purposes.
7. Do not install the unit where the exhaust vent is poin ting into any opening in a building or where the
noise may disturb your neighbors. Ensure that the vent termina tion meets the minimum distance
requirements set by code, including minimum clearances from doorways or openings.
8. P articles from flou r, aerosols, and other contaminants may clog the air vent, build up and reduce
the functions of the rota ting fan, cause improper burning of the gas, or cause damage to the water
heater. Regularly ensure that the area around the unit is dust- or debris-free. Regular maintenance is
recommended for these types of environments. Direct Ven ting is recommended.
9. Venting:
• If the boiler is used as a direct-vent appliance, the unit requires a 3 in. (76 mm)
combus tible air supply pipe. The intake pipe must be sealed airtig ht.
• Termina ting the ven ting through a sidewall is recommended for the direct-vent system.
• Running the exhaust vent and the intake pipe parallel is recommended.
• Termina ting the exhaust and intake on the same wall/surface is recommended. Termina ting in
the same pressure zone allows for pressure balancing, which prevents nuisance shutdowns.
• Only install the boiler in a heated area where below freezing temperatures cannot occur.
The warranty does not cover damage caused by freezing.
• The boiler must be securely mounted to a wall or other suitable structure.
