Water heaters are built to last longer

If durability, reliability, and versatility are the characteristics you are looking for in a water heater for your business, look no further than Giant’s line of commercial gas-fired water heaters. Our water heaters have been specially designed with more steel and better grades (low carbon, low alloy), superior burners and controls, and a wide range of gas inputs.

Giant commercial gas-fired water heaters are ideally suited for most commercial and industrial applications. They have been designed for quick and easy installation as a replacement unit or as a new installation. These commercial gas-fired water heaters can be installed as a single unit or as part of a multiple unit installation. Although used primarily as a complete water heating system, they may be combined with Giant storage tanks for additional hot water capacity.

All Giant commercial gas-fired water heaters are design certified by CSA to the harmonized standards ANSI Z21.10.3 / CSA 4.3 and meet or exceed the Thermal Efficiency requirements of ASHRAE 90.1. Each unit has a thermal efficiency greater than 80%. All models are suitable for combination potable water and space heating applications.

Benefits

LOW PROFILE AUTOMATIC FLUE DAMPER
Closes automatically when the demand for heat stops, thereby reducing stand-by heat loss. Low profile design minimizes the overall height of the water heater.

PATENTED REINFORCING STEEL COLLAR
Flue tubes are specially welded on steel collars for a longer tank life.

AUTOMATIC TEMPERATURE CONTROL
The thermostat is fully adjustable up to 180°F (82°C). It will provide years of reliable and trouble-free service at the desired water temperature. An energy cut-off (E.C.O.) is provided for abnormal conditions.

INTELLIGENT LED DIAGNOSTIC SYSTEM (Light Emitting Diode)
Designed to give a visual indication of the operational status of the water heater. This panel also identifies where to begin troubleshooting a non functional water heater.

SPARK TO PILOT IGNITION SYSTEM
Eliminates the standing pilot. Saves energy by only lighting the pilot when the thermostat calls for heat.

MULTI-FLUE DESIGN
Increases the heat transfer to the tank resulting in greater tank efficiency.

SIX (6) HIGH QUALITY MAGNESIUM ANODES
Provide excellent protection against the corrosive effects of water and extend tank life.

GLASS-LINED INNER TANK
A uniquely formulated blue cobalt glass is fused to specially treated steel at 1,600°F (871°C) to provide the best coating available against corrosion for many years. The tank is certified at a test pressure of 300 PSI (2,068 kPa) and a working pressure of 150 PSI (1,035 kPa).

LOW OVERALL HEIGHT
The new generation of commercial gas-fired water heaters has been made shorter to facilitate installation and replacement.

HIGH DENSITY FIBERGLASS INSULATION
Provides superior heat retention and energy efficiency while being environmentally friendly.

HANDHOLE CLEANOUT
Conveniently located to help clean and remove sediment accumulation inside the water heater. Standard on all models.

DRAIN VALVE
Excellent one-piece brass drain valve is installed for easy drainage.

FACTORY INSTALLED 1 ½” NPT DI-ELECTRIC NIPPLES
Maximize installation flexibility by offering models with front and rear Inlet/Outlet water connections.

MULTI-PORT, QUIET, ENERGY EFFICIENT BURNERS
The burner tray slides out easily for quick inspection and easy maintenance.

CERAMIC/REFRACTORY COMBUSTION CHAMBER
Maximizes heat transfer to the water heater.

TANK DESIGN
Maximizes installation flexibility by offering models with front and rear Inlet/Outlet water connections.

APPROVED FOR INSTALLATION ON COMBUSTIBLE FLOORING
Eliminates the need for construction of a non combustible platform. Provides greater design flexibility and safety.

FACTORY INSTALLED WIRING
All models are pre-wired at the factory so that they can be installed in conventional applications or with optional side wall power vent kits (not included).

FACTORY INSTALLED T&P RELIEF VALVE
Protects the tank from the damaging effects of excessive temperature and pressure. Size may vary depending on input.
