3 Choosing an Installation Location
Locate the vent terminal and make sure there
are no obstacles around the termination for
exhaust to accumulate or be obstructed.
Do not enclose the termination with corrugated
metal or other materials.
Carbon monoxide poisoning or fire may occur
as a result.
DANGER
• Avoid places where fires are common,
such as those where gasoline, benzene and
adhesives are handled, or places in which
corrosive gases (ammonia, chlorine, sulfur,
ethylene compounds, acids) are present.
If you do not follow the above, a fire or
explosion may result causing property
damage, personal injury or death.
• Avoid installation in places where dust or
debris will accumulate.
Dust may accumulate and reduce the
performance of the fan of the appliance.
This can result in incomplete combustion.
• Avoid installation in places where special
chemical agents (e.g. hair spray or spray
detergent) are used.
Ignition failures and malfunctions may occur
as a result.
• Do not install this Combi Boiler in a
recreational vehicle or on a boat as this may
be a Carbon Monoxide Poisoning Hazard.
• The manufacturer does not recommend
installing the Combi Boiler in an attic due to
safety issues.
If you install the Combi Boiler in an attic:
- Make sure the appliance will have enough
combustion air and proper ventilation.
- Keep the area around the Combi Boiler
clean. Dust may accumulate and reduce the
performance of the fan of the appliance.
This can result in incomplete combustion.
- A drain pan, or other means of protection
against water damage, is required to be
installed under the Combi Boiler in case of
leaks.
WARNING
Outdoor installation
• The Combi Boiler is designed for either
indoor or outdoor installation. For
information about outdoor installation,
contact Pavilion Customer Center at https://
www.peerlessboilers.com/ or 1-855-443-
8468.
Never install it in a bathroom, it may be
damaged or a fire may be caused.
Do not install in the following places
• A location where it is not free from obstacles
and stagnant air.
• Near staircases or emergency exits.
• A place where it may be threatened by falling
objects, such as under shelves.
• On common walls as the appliance will make
some operational noises while it is running.
Consideration to the surroundings
• Do not install the Combi Boiler where the
exhaust will blow on outer walls, other
walls or material not resistant to heat. Also
consider the surrounding trees and animals.
The heat and moisture from the Combi
Boiler may cause discoloration of walls and
resinous materials, or corrosion of aluminum
materials.
• Do not locate the vent termination directed
towards a window or any other structure
which has glass or wired glass facing the
termination.
• Take care that noise and exhaust gas will not
affect neighbors.
• If the appliance is installed in a location with
very high humidity, condensate may form
inside the appliance and/or cause incomplete
combustion, damage to the electrical
components, or electric leakage.
Install according to regulations and manual
• Install the Combi Boiler in an area that allows
for the proper clearances to combustible
and non-combustible construction. Consult
the rating plate on the appliance for proper
clearances.
• The Combi Boiler must be installed according
to manual.
• Before installing, make sure that the exhaust
flue termination will have the proper
clearances according to the National Fuel
Gas Code (ANSI Z223.1- latest edition) or the
Natural Gas and Propane Installation Code
(CSA B149.1).
CAUTION
Choosing an Installation Location

14
Installation in the vicinity of gas ranges,
stoves, fans, and range hoods
• Avoid installation above gas ranges or stoves.
• Avoid installation between the kitchen fan
and stove. If oily fumes or a large amount of
steam are present in the installation location,
take measures to prevent the fumes and
steam from entering in the appliance.
• Install in a location where the exhaust gas
flow will not be affected by fans or range
hoods.
CAUTION
NOT
CORRECT
CORRECT
NOT
CORRECT
• Place the appliance for easy access for
maintenance and repair.
• Do not install the Combi Boiler in a location
where the appliance will be exposed to
excessive winds.
• Locate the appliance in an area where
leakage from the appliance or connections
will not result in damage to the area adjacent
to the appliance or to the lower floors of the
structure. When such installation locations
cannot be avoided, a suitable drain pan,
adequately drained, must be installed under
the appliance. The pan must not restrict
combustion air flow.
• As with any water heating appliance, the
potential for leakage at some time in the life
of the product does exist. The manufacturer
will not be responsible for any water damage
that may occur.
• Water quality:
If this Combi Boiler will be installed in a
location where the hardness of the supply
water is high, scale Build-up may cause
damage to the Plate Heat Exchanger.
Perform suggested treatment and
maintenance measures in reference to “8.2
Water Treatment”.

5.3 Filling the condensate container
with water
5.2 Elevation Adjustment Above 2,000 ft
• Adjust the DIP switches as illustrated in the
table below, if this Combi Boiler is installed at an
altitude of 2,000 ft (610 m) or higher.
• Disconnect the electrical power and then adjust
the DIP switches.
Refer to page 68 for the location of the DIP switch
bank and how to change the DIP switches.
Failure to perform this step will result a “73” code
displayed on the Operation Display and a cease in
operation.
If this occurs, disconnect, then reconnect the
electrical power to the Combi Boiler to reset the
system. Follow the procedure described below to ensure
that the condensate container is filled with water.
Fill the condensate container by pouring approx. 10
oz. (280 mL) of water into the exhaust flue on the
top of the Combi Boiler as illustrated below.
If the vent pipe has already been installed:
After installing the condensate drain pipe, make
sure that the area around the Combi Boiler is well
ventilated; open a window or a door if necessary.
Then, operate the Combi Boiler and verify that
condensate is coming out of the condensate drain
pipe.
(During normal use of the Combi Boiler, condensate
will begin to discharge from the condensate drain
pipe within 15 minutes of use. However, depending
on the season and/or installation site conditions, it
may take longer.)
NOTE Do not change any other DIP switches.
Prior to initial start up, make sure that you fill
the condensate container with water.
This is to prevent dangerous exhaust gases from
entering the building.
Failure to fill the condensate container could
result in severe personal injury or death.
