3.4.3 Turn water supply off.
3.4.4 Disconnect power supply cable.
3.4.5 Disconnect water supply hose and delivery hoses from all discharge ports.
3.4.6 Water heater will now gravity-drain completely.
3.4.7 In very cold conditions, additional protection is accomplished by “blowing” the unit down
using a pressurized air source, to avoid any freezing.
4. PREVENTIVE MAINTENANCE:
4.1 Although Versi Heat II is a low maintenance water heating system, some periodic care is still
required for optimum operation. Outlined in the next few pages are those maintenance operations
that the operator/maintenance personnel should perform periodically. Maintenance cycle periods
naturally depend on amount of use.
4.2 Inlet Strainer (Fig. 2):
4.2.1 Versi Heat II is outfitted with an inlet “Y” strainer (Fig. 2) located at the inlet of the heater
coil. The screen in the strainer keeps contaminants from flowing into the water stream
feeding the shower booms. It also protects “wetted” mechanical components of the water
heater.
4.2.2 To clean it, loosen the screen cap on the “Y” strainer (Fig. 2):

4.2.3 Remove the cap and check the screen (Fig. 3) for contamination. Rinse the screen with
water if necessary.
Fig. 3 Strainer Gasket
4.2.4 When reassembling the strainer make sure, the screen is properly seated in both, the body
and the cap, and the gasket is properly located.
4.3 Temperature and Pressure Relief Valve (Fig. 4):
4.3.1 The temperature and pressure relief valve’s function is to protect the heater coil and by
extension, the rest of the warm water supply system from elevated temperature and
pressure. Periodically it is necessary to “exercise” it to make sure it is working correctly.
This also flushes accumulated contaminants if any from the internal valve seat area.
4.3.2 The Temperature and Pressure Relief Valve (Fig. 4) is located at the top of the water
heater and the manual activation handle is atop the valve.

4.4 Fuel filter (Fig. 7):
ATTENTION
VERSI HEAT II NEEDS TO BE OPERATED WITH FRESH AND CLEAN FUEL. STALE AND/OR
CONTAMINATED FUEL IS THE MOST COMMON SOURCE OF PROBLEMS WITH WATER HEATERS.
VERSI HEAT II NEEDS TO BE OPERATED REGULARLY TO KEEP THE FUEL SUPPLY, FRESH AND
CLEAN. IF IDLE FOR MORE THAN A MONTH, CONTACT YOUR DISTRIBUTOR FOR ASSISTANCE.
4.4.1 Fuel filter care is an essential part of Versi Heat II’s preventative maintenance procedure,
and it needs to be cleaned periodically to prevent major contamination.
4.4.2 To start the procedure, place a container under the filter to catch the fuel that will be spilled
during disassembly. Now with a 5/8” wrench (Fig. 7) loose the bolt on the top of the filter
head while firmly holding the filter bowl.
4.4.3 At times, a dry seal between the bowl and the filter head can make the bowl hard to
separate. A gentle tap on the upper part of the bowl while firmly supporting the filter will
help separate the parts.
Fig. 7 Fuel Filter
4.4.4 Remove the center bolt (Fig. 8) making sure, the red washer (see arrow in Fig. 8) is not
lost. This sealing washer prevents fuel leaks when the burner is off and air leaks into the
fuel system when the burner is on.

4.4.6 The filter is composed of several bands of wool and a center screen. It is not necessary to
disassemble the components of the element to clean it, just rinse properly. Although the
element is reusable (if properly cleansed with mineral spirits and blown clear), we
recommend one or two elements be stocked at all the time for quick turn around. Please
contact your local distributor for replacement parts.
4.4.7 A breakdown of the fuel filter is shown in Fig. 10.
Fig. 10 Fuel Filter - Breakdown
4.5 To Reassemble:
4.5.1 To reassembly the filter, simply follow the reverse order. Make sure to insert the filter
element carefully to avoid damage the screen. Verify all seals are properly seated before
placing the heater back in service to assure there are no fuel or air leaks.
4.6 Note: In cases of heavy fuel filter contamination, the entire fuel system should be checked. Severe
contamination can affect the fuel pump and/or the fuel nozzle assembly. This level of service is for
a trained oil fired burner technicians, please contact your distributor for an approved service
provider in your area.
