CHAPTER 4 - INSTALLATION REQUIREMENTS

4.1.

Vent/Combustion Air Transitions

NOTICE
LP Conversions of all Exalt models MUST be
installed using a 3" (80 mm) vent / combustion
air system.

4.1.1 3" (80 mm) to 2" (60 mm) Transitions

NOTICE
This chapter outlines the installation of 2" (60
mm) Venting and Combustion Air Piping for the
EXALT units when the vent system must transition
from the 3" (80 mm)outlet of the boiler to the 2"
(60 mm) vent system.
NOTICE
The EXALT boiler has a length of acoustic foam
already installed in the air inlet adaptor. DO NOT
remove this.
• For EXALT 110 & 155 Models only, propane
conversions require an additional acoustic foam
insert to be fitted within the combustion air
piping. Consult LP Conversion Instructions for
proper fitting.
1. The transition from 3" (80mm) vent system to 2" (60
mm) vent system must occur at the boiler vent outlet.
2. The transition from 3" (80 mm) vent to 2" (60 mm)
vent must occur in a vertical run only.
WARNING
Transition of 3" (80 mm) vent to 2" (60 mm) vent
in a horizontal run will result in pooling of the
condensate and potential vent blockage.
Failure to transition from 3" (80 mm) vent to
2" (60 mm) vent in a vertical run can result in
substantial property damage, serious injury, or
death.
3. Use a 3" (80 mm)
reducer to make
2" (60 mm) CPVC/PVC vent, see Figs. 21 and 22.
4. Use a 3" (80 mm) appliance vent adapter and 3" (80 mm)
to 2" (60 mm) reducer to make the transition to 2" (60
mm) Polypropylene vent. See Table 3 on page 7.
5. The 2" (60 mm) vent must not transition back to 3" (80
mm) vent at any point in the vent system.
6. The PVC combustion air piping shall transition from 3"
(80 mm) to 2" (60 mm) using a 3" (80 mm) x 2" (60 mm)
bell reducer and shall transition in a similar manner as
the vent system.
