Place crated boiler as close to selected location as 

possible and un-crate boiler. Boiler may be moved into 

position with appliance dolly or 2 wheel hand truck. 

Insert dolly or hand truck under left hand side of 

boiler. It is possible to slide boiler for short distance on 

smooth fl oor or surface.

Select level location central to piping systems served 

and as close to vent and air intake terminals as 

possible.

Accessibility clearances, if more stringent (i.e. larger 

clearances) than required fi re protection clearances, 

must be used for boiler installation. Accessibility 

clearances may be achieved with the use of removable 

walls or partitions.

Boiler is approved for installation in closets and on 

combustible fl oors. This boiler shall NOT be installed on 

carpeting.

Clearances shown in  Table 4 

indicate required 

clearances. Maintain minimum 1” clearance between 

combustible construction and each of left, top and 

back surfaces of the boiler. Minimum 11” clearance 

is required on right side, to allow room for induced 

draft blower. Maintain 18” clearance at side where 

passage is required to access another side for cleaning 

or servicing, inspection or replacement of parts.  Allow 

24” at front and left side and 8” at top for servicing. No 

clearances are required to venting or combustion air 

intake piping.

Install equipment in location which facilitates operation 

of venting and combustion air intake piping systems as 

described in this manual.

Advise owner to keep venting and combustion air 

intake passages free of obstructions. Both venting 

and combustion air intake piping systems connected 

to outdoors must permit fl ow through piping systems 

without restrictions for boiler operation.

Install boiler such that the automatic gas ignition 

system components are protected from water 

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

service (circulator replacement, condensate trap, 

control replacement, etc.).

This boiler requires a dedicated direct vent system. In a 

direct vent system, all air for combustion is taken directly 

from outside atmosphere, and all fl ue products are 

discharged to outside atmosphere.
Terminate combustion air and vent pipe connections in 

same atmospheric pressure zone, through roof or sidewall 

(roof termination preferred). See

 

 

Figure 12

  thru  Figure 14 , 

pages 24 and 25 for required clearances.

• Keep boiler area clean of debris and free of fl ammable 

and combustible materials, vapors and liquids.

• When vent pipe is exposed to temperatures below 

freezing, such as when it passes through an unheated 

space or when chimney is used as a raceway, vent pipe 

must be insulated with 1/2” Armafl ex or equivalent. 

In extreme cold climate areas, use ¾” Armafl ex or 

equivalent.

Solvent cements are combustible. Keep away from 

heat, sparks, and open fl ame. Use only in well ven-

tilated areas. Avoid breathing in vapor or allowing 

contact with skin or eyes. Failure these instructions 

could result in fi re, personal injury, or death.

  

• Combustion air must be clean outdoor air. Combustion 

air must not be taken from inside structure because 

that air frequently is contaminated by halogens, which 

include fl uorides, chlorides, phosphates, bromides and 

iodides. These elements are found in aerosols, deter-

gents, bleaches, cleaning solvents, salts, air fresheners, 

paints, adhesives and other household products.

• Locate combustion air inlet as far away as possible 

from swimming pool and swimming pool pump house.

• All combustion air and vent pipes must be airtight and 

watertight. Combustion air and vent piping must also 

terminate as shown in “Combustion Air and Vent 

Pipe” section.

• Vent connections serving appliances vented by 

natural draft shall not be connected into any portion 

of mechanical draft systems operating under positive 

pressure.
