SECTION 1.
General Information
1.1 Introduction
This manual provides information for the
installation and operation of MegaTherm model MT
pool heating boilers. It is strongly recommended that
all application and installation procedures be reviewed
completely before proceeding with the installation.
Consult Pentair Commercial Pool and Spa, or your
local sales representative, with any problems or
questions regarding this equipment. Experience has
shown that most problems are caused by improper
installation, not system design.
Some accessory items are shipped in separate
packages. Verify receipt of all packages listed on the
packing slip. Inspect everything for possible damage
upon delivery, and inform the carrier of any shortages
or impairments. Any such claims should be filed with
the carrier. The carrier, not the shipper, is responsible
for shortages and damage to the shipment whether
visible or concealed.
The warranty does not apply to heaters not
installed or operated in accordance with these
procedures. Consult local building and safety codes
before proceeding with work. The installation must
conform to the requirements of the authority having
jurisdiction or, in the absence of such requirements, to
the latest edition of the National Fuel Gas Code; ANSI
Z223.1, National Electrical Code ANSI/NFPA 70. In
Canada, the installation must conform with the latest
edition of CSA-B149.1 requirements.
When required by the authority having
jurisdiction, the installation must conform to
Figure 1. Heater Identification (model nomenclature).
WARNING
The MegaTherm model MT commercial pool
heating boiler must be used on potable water
only. For heating pools containing salt water, a
specially equipped heater must be used;
consult your distributor or factory
representative. The pool heating boiler must be
installed in accordance with the procedures

American Society of Mechanical Engineers safety
codes for controls and safety devices for automatically
fired heaters No. CSD-1, and in Canada CGA 3.3.
Any modification of the heater, its gas controls, gas
orifices, wiring or drafter diverter may void the
warranty. If field conditions require such
modifications, consult factory.
1.2 Heater Identification
Consult rating plate on the heating boiler. Shown
below is a breakdown of the model nomenclature.
Commercial pool heating boilers are available in two
configurations: an indoor version and an outdoor
version. Outdoor models are not available in Canada.
1.3 Primary/Secondary Pump and Piping
All models are supplied with integrally mounted
pumps. The 1825 models use a 3/4 HP pump and all
other models are supplied with 1/2 HP pumps. These
pumps are sized for the pressure drop through the heat
exchanger and through the bypass piping as shown in
Figure 10.
Any deviations from the arrangement shown may
increase the head on the pump, reduce flow and hinder
performance (see Section 2.7). For spas see Section
3.9.
This piping arrangement and the integral pump
allow hot water to be recirculated to the heater inlet,
thus raising the inlet temperature and greatly reducing
condensation.
1.4 Certifications
All models are design-certified by CSA for
natural or propane gas and conform to ASME Code
requirement for 160 PSI water pressure.
1.5 Engineering Assistance
Consult the factory or distributor regarding any
questions or problems which arise in the specification,
installation or operation of this equipment. An
experienced engineering staff is ready to assist in
assuring the proper performance and application of
this products.

SECTION 2.
Installation
2.1 Boiler Placement
The pool heating boiler must be placed to
provide specific clearances on all sides for
maintenance and inspections. There must also be
minimum distances maintained from combustible
surfaces. These clearances also apply to
noncombustible materials because the pool heating
boiler requires air circulation for proper operation.
The pool heating boiler should be mounted on a
level surface. An integral base for an installation on
combustible flooring is provided as standard
equipment on outdoor models. For indoor models,
special base rails part number 10539000 must be used
for combustible flooring.
Do not install a pool heating boiler on carpeting.
Under the national Fuel Gas Code, ANSI
Z223.1, it is permissible to place the boiler on floors
other than noncombustible when the installation
complies with the American Insurance Code. Figures
2, 3, 4 and 5 show common installation on
combustible flooring.
2.2 Installation of Indoor Boilers
Locate the pool heating boiler to provide
adequate clearance for inspection and service on all
sides. See Table 1. For alcove installation, see
Figure 6.
Install indoor heaters on a waterproof floor with
an adequate floor drain and a 6" (152mm) minimum
curb on all four sides to protect the building if heater
repairs are required. The manufacturer will not be
held liable for any water damage in connection
with this boiler.
2.2.1 Combustion Air Supply
The heater location must provide sufficient air
supply for proper combustion and ventilation of the
surrounding area as outlined in the latest edition of
ANSI standard Z223.1, and any local codes that may
be applicable. Inadequate combustion air supply may
result in incomplete combustion, sooting of the heat
exchanger, and unsafe operation of the boiler.
a. Conventional Ventilation
In the United States, the most common of these
requirements specify that boiler rooms should be
provided with two permanent air supply openings
communicating directly through the wall to outside air
one within 12 inches (305mm) of the ceiling, and the
other within
12 inches (305mm) of the floor. Each opening should
have a minimum free area of one square inch
(6.5 sq. cm) per 4,000 BTU/hr input of the total input
rating of all appliances in the enclosed area. See Table
2 for recommended air supply for each model. An

In Canada, Table 2 does not apply. Consult local
building codes or, in the absence of such
requirements, follow CSA-B149.1 standard.
