17.6 - Condensate trap and
neutralizing box maintenance and
cleaning
The condensate trap and neutralizing box must be checked every
year and cleaned if required. Follow the steps below to properly
inspect, recharge or substitute condensate neutralizing box and
media:
Monitor the level of the neutralization media in the box periodically.
The pH can be checked from the test port “D” (Figure 17-11). Check
the pH level every three months for the first year. Use a suitable pH
test strip paper or an electronic pH meter for precise measurement.
The frequency of checking the pH level can be reduced to every
six months or every year depending on the readings obtained
compared to local water authority requirements. The neutralizing
media should be replaced when the pH level drops below the
minimum level of the local water authority. For replacement media
contact your local sales representative. How to operate:
1. follow the steps in Section 17.2 to gain access to the condensate
box;
2. pull out for 2 inches the condensate box “A” (Figure 17-10);
3. place a bucket (Min. 2 gallons) below connection “E” and “F”
(Figure 17-11);
4. Disconnect connections “E” and “F” (Figure 17-11);
CAUTION!!!
Disconnecting connection “E” and “F” (Figure
17-11) condensate water will immediately exit and must
be collected into the presaid bucket. Leaking condensate
water may cause severe property damage.
5. pull completely out the condensate box “A” from heater;
6. open cover “C” (Figure 17-11) in the upper direction;
7. inspect the condensate box making sure the collection box is
intact;
8. examine neutralizer media and refill as necessary with fresh
media;
9. fill with fresh water until the water begins to flow out of drains “E”
and “F” (Figure 17-11) ;
10. re-install the condensate box;
WARNING!!!
The condensate collection box must
be filled with water to prevent flue gas emissions from
escaping during unit operation. Failure to comply with
this requirement can result in excessive levels of carbon
monoxide which can cause severe personal injury or
death!
11. open the manual gas shutoff valve;
12. restore electrical power to the heater.
WARNING!!!
The condensate neutralizer box must
be kept correctly installed into the unit, like shown in
Figures 3-3 through 3-6 item “8”. Correctly reinstall
the condensate collection into its position. Incorrectly
reinstall the condensate collection box into position will
result in combustion gases entering the room. This can
result in excessive levels of carbon monoxide which can
cause severe personal injury or death!
