GENERAL SAFETY INFORMATION EXTERNAL DAMAGE Do not operate the water heater until it has been fully checked out by a qualified technician, if the water heater: • Has been exposed to fire or damage. • Displays evidence of sooting. • Produces steam or unusually hot water. If the water heater has been subject to flooding it must be replaced.
• Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference. • Do obtain new warning and instruction labels for placement on the blanket directly over the existing labels. • Do inspect the insulation blanket frequently to make certain it does not sag, thereby obstructing combustion air flow.
If the unconfined space is within a building of tight construction (building using the following construction: weather stripping, heavy insulation, caulking, vapor barrier, etc.), air for combustion and ventilation must be obtained from outdoors. The installation instructions for confined spaces must be followed. CONFINED SPACE When drawing combustion air from inside a conventionally constructed building to a confined space, such a space shall be...

joints, including joining the pipe to the Termination (PVC Material). If local codes do not allow the use of the PVC termination when a material other than PVC is used for venting, then an equivalent fitting of that material may be substituted if the screen in the PVC terminal is removed and inserted into the new fitting.
WARNING CONDENSATE ALSO DRAINS FROM TWO LOCATIONS ON THE BLOWER ASSEMBLY AS SHOWN IN FIGURE 5. A CONDENSATE HOSE MUST BE SECURED TO FORM A "TRAP" AS SHOWN IN FIGURE 5 FOR THESE CONDENSATE DRAIN CONNECTIONS. THESE TWO HOSES MAY BE CONNECTED TOGETHER.

8. Take the end of the tube at the bottom of the floor and route it to a suitable drain. This will provide an area where the condensate can drain without affecting the area around the appliance. 9. Once installed along with the rest of the vent configuration, make sure to operate the unit through at least one heat up cycle to ensure there is no leakage around the hose barb or any joints of the VAA or vent pipe system.
VENT PIPE PREPARATION 1. INITIAL PREPARATION A. Make sure the solvent cement you are planning to use is designed for the specific application you are attempting. B. Know the physical and chemical characteristics and limitations of the PVC and CPVC piping materials that you are about to use. C.
Depth-of-entry mark Marking the depth of entry is a way to check if the pipe has reached the bottom of the fitting socket in step F. Measure the fitting depth and mark this distance on the pipe O.D. You may want to add several inches to the distance and make a second mark as the primer and cement will most likely destroy your first one.
