VENTING

WARNING

THE INSTRUCTIONS IN THIS SECTION ON VENTING MUST BE FOLLOWED TO AVOID CHOKED COMBUSTION OR RECIRCULATION OF FLUE GASES. SUCH CONDITIONS CAUSE SOOTING OR RISKS OF FIRE AND ASPHYXIATION.

WARNING

NEVER OPERATE THE HEATER UNLESS IT IS VENTED TO THE OUTDOORS AND HAS ADEQUATE AIR SUPPLY TO AVOID RISKS OF IMPROPER OPERATION, FIRE, EXPLOSION OR ASPHYXIATION.

CAUTION

DO NOT TERMINATE THE VENTING WHERE NOISE FROM THE EXHAUST OR INTAKE WILL BE OBJECTIONABLE. THIS INCLUDES LOCATIONS CLOSE TO ORACROSS FROM WINDOWS AND DOORS.

FIGURE 33

VENT TERMINALS

The vent system must terminate so that proper clearances are maintained as cited in local codes or the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54.

The SRT80-120NE series is designed with an internal vent construction. The exhaust vent terminal and the inlet air terminal are located on the sides of the appliance. Do not add vent pipe to the appliance, see Figure 33.

Assure the exhaust vent terminal is not in a public area where the hoods are exposed. The exhaust vent terminal gets very HOT during operation and can cause burns. Please use caution when working around the exhaust vent terminal.

It is imperative that the area around the vent terminal hoods are kept clear from obstructions so plenty of fresh air is available for combustion.

The vent shall terminate a minimum of 12" (30.5 cm) above expected snowfall level to prevent blockage of vent termination.

WARNING

USE ONLY THE VENT TERMINALS SUPPLIED WITH THIS UNIT. TERMINATION OF A VENT SYSTEM WITH A DEVICE OTHER THAN THE SUPPLIED VENT TERMINATIONS WILL AFFECT SYSTEM PERFORMANCE AND RESULT IN A SAFETY HAZARD.

PRESSURE SWITCHES

The SRT80-120NE is provided with three pressure switches. These switches are essential to the safe and proper operation of the unit. All switches are wired in series. The controller is set up to shut the unit down whenever there is a failure of any of the switches.

CAUTION

THE WATER HEATER IS POLARITY SENSITIVE. BEFORE APPLYING ELECTRICITY TO THIS HEATER BE CERTAIN THAT SUPPLY NEUTRAL WIRE TO GROUND CHECK INDICATES ZERO VOLTAGE.

GAS PIPING

Contact your local gas service company to ensure that adequate gas service is available and to review applicable installation codes for your area.

Size the main gas line in accordance with Table 3. The figures shown are for straight lengths of pipe at 0.5 in. (125 kPa) W.C. pressure drop, which is considered normal for low pressure systems. Note that fittings such as elbows and tees will add to the pipe pressure drop.

CAUTION

DO NOT USE FLEXIBLE GAS PIPING.
