Installation; General - Hatco Powermite PMG-100 Installation And Operating Manual

General

WARNING
FIRE OR EXPLOSION HAZARD:
• Unit must be installed by qualified, trained installers.
Installation must conform to all local plumbing and
gasfitting codes. Installation by unqualified personnel
will void the unit warranty and may lead to fire or
explosion causing property damage, personal injury, or
death. Check with local plumbing inspectors for proper
procedures and codes.
• The gas used with this unit must be the type specified
on the spec plate on this unit. To avoid personal injury
or damage to the unit, never use any other than the
specified gas.
• The heater and its gas connection must be leak tested
before placing the booster heater in operation. Use
soapy water or commercially available fluid for leak
test. DO NOT use open flame to test for leaks.
• If the information in these instructions is not followed
exactly, fire or explosion may result causing property
damage, personal injury, or death
ELECTRIC SHOCK HAZARD:
• Unit must be installed by qualified, trained installers.
Installation must conform to all local electrical codes.
Installation by unqualified personnel will void the unit
warranty and may lead to electric shock or burn, as well
as damage to unit and/or its surroundings. Check with
local electrical inspectors for proper procedures and
codes.
• Unit is not weatherproof. Locate unit indoors where
ambient air temperature is a minimum of 70°F (21°C).
• If an external electrical source is utilized, the appliance,
when installed, must be electrically grounded in
accordance with local codes, or, in the absence of local
codes, with the National Electrical Code, ANSI/NFPA 70,
and CSA C22.1, Electrical Code.
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.
Install booster water heater in a horizontal position with
the base parallel to the floor and the inlet connection at the
lowest point. Improper installation could create an unsafe
condition.
Install booster water heater as close as possible to a
commercial dish machine. Employ re-circulation if distance
between water heater and dish machine exceeds National
Sanitation Foundation (NSF) specifications of five (5) linear
feet (1524 mm).
Refer to the BOOSTER HEATER SIZING CHART in this
manual to ensure proper sizing and avoid personal injury
and/or damage to the booster heater.
BURN HAZARD: Valves supplied by Hatco are designed for
high temperature commercial operation. Do not substitute
Hatco valves with valves designed for domestic water
heaters.
Form No. PMG100200M-0918
CAUTION
Incoming water temperature should be minimum of 85°F
(29°C). Damage to the heater can occur if water is cooler
than 85°F (29°C).
Unit is not weatherproof. Unit must be located indoors
where ambient air temperature is constant and is a
minimum of 70°F (21°C).
If water supply pressure to the booster inlet is over
20 psi (138 kPa) during flow, install pressure reducing
valve with built-in bypass (Hatco P/N 03.02.004.00) for
proper operation of dish machine rinse nozzles.
NOTE: The pressure reducing valve must be the type equipped
with a high pressure bypass, as supplied by Hatco.
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
CSA-B149.1, Natural Gas and Propane Installation Code, and
CSA-C22.1 Electrical Code, and/or local installation codes.
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 P/N 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 dishmachine.
NOTE: Employ external recirculation if distance between
booster and dishmachine exceeds the NSF specification
of 5' (1.5 m).
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.
