LP-294 REV. 2.20.14
The building owner is responsible for keeping the exhaust and intake terminations free of snow, ice, or other potential blockages, as
well as scheduling routine maintenance. Failure to keep the vent piping terminations clear and properly maintain the boiler could result
in property damage, severe personal injury, or death.
For each floor containing bedroom(s), a carbon monoxide detector and alarm shall be placed in the living area outside the bedrooms,
as well as in the room that houses the boiler. Detectors and alarms shall comply with NFPA 720 (latest edition). Failure to comply with
requirements for detectors and alarms could result in property damage, severe personal injury, or death.
DETERMINE LOCATION OF CONDENSATE PIPING
This boiler is a high efficiency appliance, and produces condensate: a by-product of the combustion process. A condensate collection
system with an internal float switch monitors the condensate level to prevent it from backing into the combustion system. There is a ¾”
PVC pipe connection provided to connect the outlet of the collection system to a drain or condensate pump.
CONDENSATE NEUTRALIZATION
Condensate from the boiler is slightly acidic with a pH of 3.2 - 4.5. To avoid long term damage to the drainage system and to meet local
code requirements, HTP recommends neutralizing the condensate with a Condensate Neutralizer Kit (Part # 7450P-212 for ELP-
110/199). The neutralizer kit connects to the drain system and contains limestone chips that neutralize the pH level of the water vapor.
The neutralizer kit should be checked annually and the limestone chips replenished if necessary. When replacing the limestone chips,
take care to ensure chips are
no smaller than ½” to avoid blockage in condensate piping (refer to Figure 12 for piping of the condensate
neutralizer.)
When installing a condensate pump, select one approved for use with condensing boilers and furnaces. The pump should have an
overflow switch to prevent property damage from condensate spillage.
When servicing is complete, you must make sure the clean out port cap is replaced securely. Failure to do so will cause exhaust gas to
leak and will result in serious injury or death.
The condensate line must remain unobstructed, allowing free flow of condensate. If condensate freezes in the line, or if line is
obstructed in any other manner, condensate can exit from the tee, resulting in potential water damage to property.
It is very important that condensate piping be no smaller than ¾”. Use a tee at the condensate connection with a branch vertically up
and open to the atmosphere, so as not to cause vacuum or overpressure that could obstruct the flow of condensate from the boiler. To
prevent sagging and maintain pitch, condensate piping should be supported with pipe supports.
NOTE: Blow water into the condensate collector to remove any foreign matter that may block the line.
NOTE: To allow for proper drainage on larger horizontal condensate runs, tubing size may need to increase to 1 inch and a second line
vent may be required.
