Condensate Removal System - Pioneer PHR100-55 Instruction Manual

fans, such as range hoods and bathroom exhausts, at maximum speed. Do not operate a summer
exhaust fan. Close all fireplace dampers.
4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust the thermostat
so the appliance will operate continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the
flame of a match or candle or smoke from a cigarette.
6. After it has been determined that each appliance remaining connected to common venting system
properly vents when tested as outlined, return doors, windows, exhaust fans, fireplace dampers and any
other gas burning appliance to their previous condition of use.
7. Any improper operation of the common venting system should be corrected to conform to the National
Fuel Gas Code, ANSI Z223.1. When resizing any portion of the common venting system, the system
should approach the minimum size as determined using the appropriate tables in Appendix G in the
National Fuel Gas Code, ANSI Z 223.1.
J. CONDENSATE REMOVAL SYSTEM
This condensing high efficiency appliance has a condensate removal system. Condensate is water vapor
derived from combustion products, similar to an automobile when it is initially started. It is very important
that the condensate line is sloped down away from the heater and to a suitable drain.
If the heater condensate outlet is lower than the drain, you must use a condensate removal pump (kit
554200 available from HTP). If required by local authorities, a condensate filter of lime crystals, marble, or
phosphate chips will neutralize slightly acidic condensate. This can be installed in the field and purchased
from HTP (7450P-212).
The condensate line must remain unobstructed. If allowed to freeze in the line or obstructed in any other
manner, condensate can exit from the water heater tee, resulting in potential water damage to property.
When installing a condensate pump, select one approved for use with condensing heaters and furnaces.
The condensate pump should have an overflow switch to prevent property damage from spillage.
Condensate from the heater will be slightly acidic (pH from 3.2 to 4.5). Install a neutralizing filter if
required by local codes.
Plastic tubing must be the only material used for the condensate line. Steel, brass, copper or other
materials will be subject to corrosion or deterioration. A second vent may be necessary to prevent a
condensate line vacuum lock if a long horizontal run is used. An increase in condensate line diameter
may be necessary to allow condensate to drain properly. Support of the condensate line may be
necessary to avoid blockage of the condensate flow.
