INTRODUCTION

Hatco Powermite Gas Booster Heaters are
instantaneous fin tube type heaters designed to
boost the temperature of regularly available hot
water, usually 110°F to 150°F (43°C to 66°C) up to
180°F (82°C). Water at 180°F (82°C) can be used
as sanitizing rinse water in commercial dishwashers
in accordance with Health Codes and National
Sanitation Foundation Standard #5.

The Hatco Gas Booster Heater is design certified
by CSA International and tested under the

MODEL DESCRIPTION

The Hatco Powermite Gas Booster Heater is
designed to maintain a temperature of 180°F
(82°C) water required for the rinse cycle of a
commercial dishwasher. An inlet water temperature
of at least 110°F (43°C) will produce optimum
results (See Capacity Chart and Booster Heater
Sizing Chart in SPECIFICATIONS).

After the necessary power, water and gas
connections are completed, start the unit by turning
on the toggle switch located on the lower front base.
The water circulating pump will start at this time.
Providing the operating and safety controls are
satisfied, the ignition module will begin a 20 second
safety pre purge, next it will energize the spark
igniter and turn on the gas for the pilot. The igniter
will spark for about 90 seconds or until proof of fire.
If there is a confirmed pilot fire, and the water
temperature is below the setpoint, the unit will go
into full burn. The unit will stay in full burn until the
desired setpoint temperature is met, then the burner
will shut off. During standby periods of limited use,
the burner will cycle on only to replace standby
water temperature loss. If for some reason the unit
did not ignite there is an automatic 5 minute delay
before the unit attempts to ignite again.

If the unit overheats above the setpoint temperature,
the safety high limit will open, shutting down the
burner, locking out the controller, and turning on the
alarm pilot light. In order to reset the unit, turn the
unit off and depress the reset button on the
appropriate high limit switch, the tank high limit is
located behind front panel on the left hand side of
the vertical control panel. The heat exchanger high
limit is located on the front of the heat exchanger.
The switches will not reset until the temperature has
dropped to a safe level. This unit must remain off for
at least 10 seconds before it can be restarted.

NOTE: The operating thermostat control is factory
preset at 190°F (88°C).

NOTE: The circulator pump will stay on as long as
the toggle switch is in the ON position.

SYSTEM OVERVIEW

ALL MODELS

Water enters the booster heater at the inlet water
connection and flows into the stainless steel tank. It
then is pumped through the finned tube heat
exchanger where it is heated to the proper
temperature. The heated water then returns back to
the top half of the stainless steel tank for supply to
the dishwashing machine. Water that is not
immediately used by the dishwashing machine is
recirculated through the heat exchanger by the
water pump.

This system is designed to assure the availability of
the proper temperature water at the heater outlet.

All Hatco booster heaters are warranted to be free
of defects in material and workmanship under
normal use and service, and when installed in
accordance with factory recommendations.

NOTE: Hatco Booster Water Heaters are approved
for use with commercial dishwashers only.

INSTALLATION

GENERAL

Code Requirements

Installation must be in accordance with local codes,
or in the absence of local codes, with the latest
edition of the National Fuel Gas Code, ANSI Z223.1,
the National Electrical Code, ANSI/NFPA 70.
Canadian installations should conform with CSA­B149.1, Natural Gas and Propane Installation Code,
and CSA-C22.1 Electrical Code, and/or local
installation codes. {Les installations canadiennes

doivent se conformer aux CODES
D’INSTALLATION CSA-B149.1, Natural Gas and
Propane Installation Code, et CSA-C22.1 Electrical
Code, et/ou aux codes locaux d’installation.}

NOTE: In the Commonwealth of Massachusetts,
Hatco Booster Heaters shall be installed by a
licensed plumber and gasfitter.

NOTE: The Commonwealth of Massachusetts
requires that if a water treatment system is
installed in line with the Hatco Booster Heaters,
a water backflow protector shall also be
installed.

NOTE: If a check valve or water backflow protector
is installed and cannot be removed install a back
pressure relief valve, Hatco part number

03.02.039.00, set at 125 psi (862 kPa) on the
incoming line between the pressure reducing valve
and the inlet to the booster heater. Discharge must
be to open site drain.

For the most effective operation, install the Hatco
Gas Booster Heater as close as possible to the
dishwashing machine.

NOTE: Employ external recirculation if distance
between booster and dishwasher exceeds the
National Sanitation Foundation specifications of five
(5) feet (1.5 m).

WARNING
To assure proper operation and avoid a
possible unsafe condition, the booster heater
must be installed in a horizontal position with
the base parallel to the floor and the inlet

connection at the lowest point.

The Booster Heater must not be installed directly on
carpeting, but on top of a metal, wood (or
equivalent) panel extending beyond the full width
and depth of the booster heater by at least 3"
(76 mm) in any direction or, if the heater is installed
in an alcove, the entire floor must be covered by the
panel. The panel must be strong enough to carry the
weight of the heater when full of water.

Adequate front clearance is required to allow for
accessibility to the control compartment.

The booster heater should be located in an area
where leakage of the tank or connections will not
result in damage to the area adjacent to the heater
or to lower floors of the structure. When such
locations cannot be avoided, it is recommended that
a suitable drain pan, adequately drained, be
installed under the booster heater. The pan must not
restrict combustion air flow.

CAUTION
Unit is not weatherproof. For safe and proper
operation the unit must be located indoors
where the ambient air temperature is constant
and is a minimum of 70°F (21°C).

INSTALLATION

WARNING/CAUTION
The flow of air to the heater for combustion
and ventilation must not be obstructed. Air
vents on the bottom and side of the unit
should never be blocked. All panels should be
in place during normal operation for optimal
performance and safety.

WARNING/CAUTION
This unit is designed to vent to the outside or
into an open Equipment Hood, and is intended
for commercial food service water heating
only. IT IS NOT FOR RESIDENTIAL

USE. See

VENT section of this manual.

WARNING/CAUTION
Flue gases exit top side or back of this unit and
must not be obstructed, specified clearances
must be maintained for safe operation. See
VENT section for vent piping alternatives.

Combustion/Ventilation Air

The booster heater must be located in an area
which allows for an adequate supply of air for proper
combustion and ventilation in accordance with
Section 5.3 and 7.2.2 of the National Fuel Gas Code
NFPA54/ANSI Z223.1 or applicable provisions of
the local building codes. Only a single booster
appliance may be installed in this manner.

Installations under the jurisdiction of Canadian
CSA-B149.1, Natural Gas and Propane
Installation Code, require a gas interlock tied
into the ventilation hood system. {Les

installations sous la juridiction des CODES
D’INSTALLATION canadiens CSA-B149.1,
Natural Gas and Propane Installation code,
nécessitent un verrouillage réciproque de gaz
raccordé au système de capot de ventilation.}

INSTALLATION

High Altitude Installation and Operation

Atmospheric conditions at elevations above 2000 ft.
(610 m) have an effect on the performance of most
gas fired products. For this reason, historical models
for altitude de-rating were developed for gas
appliances with atmospheric burners. The National
Fuel Gas Code, ANSI Z223.1 is an accepted model
which requires a de-rating of 4% per 1000 ft.
(305 m) elevation when no testing to the contrary
exists for that product. This could require modifying
the equipment and adjusting settings in the field to
achieve de-rating. Testing has shown this to be a
very conservative approach.

Manufacturers discourage unnecessary field
adjustments in order to maintain a level of
performance and quality designed into the product.
For these and other reasons, testing was
underwritten through CSA International to verify an
improved satisfactory performance with little or no
modification to effect input rate or control. The
following text and charts are a result of this testing
and should be used during application sizing and
installation.

• The PMG-100 can operate at better levels than

ANSI Z223.1 without manifold pressure setting
adjustments or orifice changes up to the 8500 ft.
(2593 m) elevation for both natural gas and liquid
propane gas units. Above this level only a slight
decrease in manifold pressure may be needed to
meet the approved BTU rate. This is shown in
the Altitude Summary chart. Also, note that GPH
capacity will be reduced and a guideline is given

as to the percent of sea level capacity expected.
For Canadian installations between 2000-4500 feet
(610-1370 m) de-rate unit by 10% to 94,500 BTU.

{Pour les installations au Canada entre 610 et 1370
m (2000 et 4500 pi) reclassifier l’appareil de 10% à
94 500 BTU.}

• PMG-200 will require orifice changes at levels

shown in the Altitude Summary chart. This
follows the 4% de-rating scheme outlined in
ANSI Z223.1 for both natural gas and liquid
propane gas. Also note that the GPH capacity
will be reduced and a guideline is given as to the

percent of sea level capacity expected.
For Canadian installations between 2000-4500 feet
(610-1370 m) de-rate unit by 10% to 175,500 BTU.

{Pour les installations au Canada entre 610 et
1370 m (2000 et 4500 pi) reclassifier l’appareil de
