PREINSTALLATION

1. PREINSTALLATION
Read carefully, study these instructions before beginning work.
This boiler must be installed by a qualified contractor.
The boiler warranty can be voided if the boiler is not installed, maintained and serviced correctly.
The equipment must be installed in accordance with those installation requirements of the authority having
jurisdiction or, in the absence of such requirements, to the current edition of the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or CAN/CSA B49.1, Natural Gas and Propane Installation Code .
Where required by the authority having jurisdiction, the installation must conform to American Society of Mechanical
Engineers Safety Code for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1.
A. ACCESSIBILITY CLEARANCES
Install boiler not less than 24" (610 mm) between the left
side, top, and front of the boiler and adjacent wall or
other appliance, when access is required for servicing.
B. CLEARANCE FROM COMBUSTIBLE
CONSTRUCTION
The design of this boiler is certified for closet installation
with the following clearances:
1. 6" (152 mm) between right side, front and
combustible construction.
2. 12" (305 mm) between top of jacket and combustible
construction.
3. 1" (25 mm) between left side, rear and combustible
construction.
4. 2" (51 mm) between vent pipe and combustible
construction.
5. Zero clearance between wall thimble and combustible
construction.
6. This boiler is design certified for use on combustible
flooring.
DANGER
Do not install this boiler on carpeting. Boiler
installation on carpeting is a fire hazard. Install this
boiler on non-combustible flooring or use a
combustible floor pan to install this boiler on other
non-carpeted flooring.
WARNING
Liquefied Petroleum (LP) is heavier than air and may
collect or "pool" in a low area in the event of a leak
from defective equipment. This gas may then ignite,
resulting in a fire or explosion.

NOTICE
C. INSTALLATION SURVEY
For new and existing installations, a Water Installation
Survey is available from PB Heat, LLC. The survey will
provide information on how a hot water boiler works with
your specific system and will provide an overview of hot
water system operation in general.
You can also use this survey to locate system problems
which will have to be corrected. To obtain copies of the
Water Installation Survey, contact your PB Heat
representative or download it from PeerlessBoilers.com.
D. PLANNING THE LAYOUT
Prepare sketches and notes of the layout to minimize the
possibility of interferences with new or existing
equipment, piping, venting and wiring. Review limitations
on vent pipe, vent terminal, and air inlet pipe locations
and ventilation air requirements in Section 4.
E. MASSACHUSETTS INSTALLATIONS
Massachusetts requires manufacturers of Side Wall
Vented boilers to provide the following information
from the Massachusetts code:
A hard wired carbon monoxide detector with an
alarm and battery back-up must be installed on
the floor level where the gas equipment is to be
installed AND on each additional level of the
dwelling, building or structure served by the side
wall horizontal vented gas fueled equipment.
In the event that the side wall horizontally vented
gas fueled equipment is installed in a crawl space
or an attic, the hard wired carbon monoxide
detector with alarm and battery back-up may be
installed on the next adjacent floor level.
Detector(s) must be installed by qualified licensed
professionals.
