2.1

locating the Unit

The NeoTherm unit may be installed indoors or

outdoors. The unit may only be installed outdoors

in a location which will never experience freezing

temperatures. Choose a location for the unit which

allows clearances on all sides for maintenance and

inspection. See Table 1. Always install the unit on a

firm, level surface. Level the unit using the leveling

feet.
The unit should not be located in an area where

leakage of any connections will result in damage to

the area adjacent to the appliance, or to lower floors

of the structure.
When this type of location is not available, install

a suitable drain pan, adequately drained, under the

appliance.
The appliance is design-certified by CSA-

International for installation on combustible flooring;

in basements; in closets, utility rooms or alcoves

NeoTherm boilers must never be installed on
carpeting.

The location for the appliance should

be chosen with regard to the vent pipe lengths and

external plumbing.
The unit shall be installed such that the gas ignition

system components are protected from water

(dripping, spraying, rain, etc.) during operation and

service (circulator replacement, control replacement,

etc.).
When vented vertically, the NeoTherm must be

located as close as practical to the vertical section

of the vent. If the vent terminal and/or combustion

air terminal terminate through a wall, and there is

potential for snow accumulation in the local area,

both terminals should be installed at an appropriate

level above grade or the maximum expected snow

line.
The dimensions and requirements that are shown in

Table 1 should be met when choosing the locations

for the appliance.

locating Unit for Correct Vent

Distance from outside Wall or

roof termination

The forced draft combustion air blower in the

appliance has sufficient power to vent properly when

the guidelines in Table 2

are followed.

note -

When located on the same wall, the

NeoTherm combustion air intake terminal must

be installed a minimum of 12” below the exhaust

terminal. There must also be a minimum horizontal

Installations in the U.S. require exhaust vent pipe that is PVC or
CPVC complying with ANSI/ASTM D1785 F441, polypropylene
complying with ULC-S636, or stainless steel complying with
UL1738. Installations in Canada require exhaust vent pipe that is
certified to ULC S636.
Intake (air) pipe must be PVC or CPVC that complies with ANSI/
ASTM D1785 F441, ABS that complies with ANSI/ASTM D1527,
stainless steel, or galvanized material.
Closet and alcove installations do not allow the use of PVC under
any circumstances
To calculate max equivalent length, measure the linear feet of the
pipe, and add 5 feet

(1.5 m)

for each elbow used.
