Boiler Installation Location Requirements:

The installation of this boiler when installed using room air must comply to NFPA 54.

The flue gas pipes must be connected to the outside wall and/or the outside roof. (“Flue gas instructions”
manual.)

The installation area must be dry and frost-free.

The boiler has a built-in fan that will generate noise, depending on the total heat demand. The boiler
location must minimize any disturbance this might cause. Preferably mount the boiler on a solidly
constructed wall or stand.

There must be sufficient lighting available in the boiler room to work safely on the boiler.

When a boiler is positioned at the highest point of the installation, the supply and return pipes must first
protrude 20” above the top of the boiler, before these pipes go to the installation side. In other words, the
water level must always be 20” above the top of the boiler and an automatic air vent must be installed in
the supply or return pipe. It is recommended to install a low water cut off above the boiler, when the boiler
is installed above the system or at the highest point in the installation.
 Do not install the boiler in a location where it will be exposed to temperatures 100 °F or higher.
 Do not install the boiler in a location where it will be exposed to high levels of humidity and moisture or
where condensation might fall onto the boiler.

Make sure there is an open connection with the sewer to drain the condensate. This connection must be
lower than the condensate drains level of the
boiler, if not a condensate pump will be required.

Do not locate the boiler in an area which contains corrosive or other contaminants as outlined in section
9.6 tables 9-12 and 9-13
 When considering installation locations consideration must be given to the combustion air supply
whether using indoor air or sealed combustion.
 Do not allow the combustion air to come from a source or area which contains corrosive or other
contaminants as outlined in section 9.6 tables 9-12 and 9-13
The boiler must be positioned and installed by a qualified installer or the gas company in accordance with all
applicable standards, local codes and regulations. Commissioning of the boiler must be done by a qualified
installer or technician, who is trained for this type of boiler.
In the Commonwealth of Massachusetts this boiler must be installed by a licensed Plumber or Gas Fitter.
