Read all instructions before installing. Follow
all instructions in proper order to prevent
personal injury or death.
Inlet and outlet pipe and ttings provided
by installer.
1. Install 3” diameter PVC or CPVC pipe and elbow on air
inlet of boiler.
2. Install 3” screen in opening of elbow.
Installation of pipe and elbow in inlet is to
prevent objects from inadvertently entering or
blocking air inlet.
3. Use the template to cut appropriate hole in wall for exhaust.
Use only the exhaust hole!
4. Run the exhaust vent piping to the wall in accordance with
the instructions shown on the following pages.
5. Install appropriate size bird screen in end termination.
e boiler can use inside air if no contaminants are present in
the boiler space. (If contaminants are likely to be present, install
the boiler as a direct vent appliance, using the appropriate vent
instructions in the boiler manual.)
e boiler room must be tted with combustion air openings
large enough to provide air for all appliances in the room. Use the
following information to size the openings. Ensure the installation
complies with all applicable codes and standards.
Air openings provide for ventilation (as well as combustion air)
to prevent overheating of the boiler controls and boiler space.
Air is also needed for other appliances located in the same space.
Use Figure29,page26, selecting the appropriate installation
conditions.
Air openings must be sized to handle all appliances
and air movers (exhaust fans, etc.) using the air
supply.
e sizing given in Figure29,page26 is based on the National
Fuel Gas Code, ANSI Z223.1/NFPA 54 - latest edition, allowing
adequate air openings for gravity-vented gas appliances
(Category I) in addition to that needed for the ECO Tec boiler.
Installers must add in ECO Tec's BTU rating into
calculations in Figure29,page26, along with all the
other appliances in the room.
e air openings recommended in Figure29,page26 will allow
adequate ventilation and combustion air provided the boiler room
is not subjected to negative pressure due to exhaust fans or other
mechanical ventilation devices.
Refer to the National Fuel Gas Code for dealing with other
conditions.
