Page 4: Extended Non-Use
OPERATION OF THESE FANS CAN PRODUCE A NEGATIVE DRAFT IN THE AREA OF THE WATER HEATER PREVENTING THE PRODUCTS OF COMBUSTION FROM EXHAUSTING THROUGH THE CHIMNEY OR VENT PIPE. The venting of the water heater should be inspected by a qualified service technician at the time of installation and periodically thereafter to ensure a down-draft condition does not exist. -
Page 5: High Limit Switch
In the event of high limit switch operation, the appliance cannot be restarted unless the water temperature is reduced to approximately 120°F (49°C). The high limit reset button on the front of the control then needs to be depressed. Continued manual resetting of high limit control, preceded by higher than usual water temperature is evidence of high limit switch operation. -

FIGURE 6 -ILLUSTRATION OF MINIMUM CLEARANCES TO COMBUSTIBLES UNCONFINED SPACE In buildings of conventional frame, brick, or stone construction, unconfined spaces may provide adequate air for combustion, ventilation and draft hood dilution. If the unconfined space is within a building of tight construction (buildings using the following construction: weather stripping, heavy insulation, caulking, vapor barrier, etc.), air for combustion, ventilation and draft hood dilution must be obtained from... -

• Where a separate vent connection is not available and the vent pipe from the heater must be connected to a common vent with an oil burning furnace, the vent pipe should enter the smaller common vent or chimney at a point above the large vent pipe. -
Page 9: Gas Piping
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 2. The figures shown are for straight lengths of pipe at 0.5 in. W.C. pressure drop, which is considered normal for low pressure systems. -

plate. The regulator is factory adjusted to deliver gas to burner at correct water column pressure allowing for a nominal pressure drop through the controls. The minimum gas supply pressure for input adjustment must not be less than 4.5" w.c. for natural gas. Do not subject the combination gas valve to inlet gas pressures of more than 14.0"... -
