IMPORTANT SAFETY NOTE It takes only 5 seconds of skin contact with 140°F water to cause a second degree burn! You must protect against high water temperatures at all lavatories, tubs, showers and other points of hot water contact. Accidental scalding from high water temperatures is a greater risk in some types of installations. Some examples are: HOMES FOR THE MENTALLY HANDICAPPED HOMES FOR THE PHYSICALLY HANDICAPPED HOSPITALS AND NURSING HOMES ELDER CARE FACILITIES AND RES

8. Do not install on carpet or other combustible floor coverings. If installation over a combustible floor is required, follow these guidelines: Use a base of hollow clay tile or concrete blocks from 8" to 12" thick and extending 24" beyond the sides. Place the blocks in line so that the holes line up horizontally to provide a clear passage through the blocks. Install 1/2” fireproof millboard with a 20-gage sheet metal cover over the block base. Center the unit on the base.

TWO WATER HEATERS WITH REVERSE RETURN PIPING 6 CONDENSATE DRAIN, TRAP & DISPOSAL The POWER VT PLUS water heater is designed to produce significant amounts of condensate because of its high efficiency. Condensate occurs naturally when water vapor in combustion gases is cooled below the dew point. Two 3/4” NPT drain connections are provided. A trap with three inches of standing water below the bottom of the heater (3” above the base of the I-Beam skids), and no higher than the bottom o

Condensate Piping and Trap with Optional Condensate Neutralizer 6.1 Condensate Neutralization System (optional) Although only slightly acidic (3-5 PH), condensate can be routed through an optional Condensate Neutralization System (see image below) to become pH neutral allowing for disposal into any drain or sewer system without concern for corrosion. Condensate slowly flows through a neutralization bath filled with renewable crushed limestone becoming neutralized thus avoiding chemica

7.7 Gas Connection 1. Safe operation of unit requires adequate gas supply with the required static and dynamic (flow) pressures. Actual piping selection depends on many variables that must be carefully considered by the gas piping system designer. Do not select gas pipe sizes based only on the supplied tables. These tables are for use by the gas piping system designer as a reference in checking pipe size selections. 2. Gas pipe size may be larger than heater connection. 3. Installation of
