5.1 Condensate Neutralization System (optional)

Although only slightly acidic (3-5 PH), condensate can be routed through an optional Condensate Neutralization

System (see image below) to become pH neutral allowing for disposal into any drain or sewer system without

concern for corrosion. Condensate slowly flows through a neutralization bath filled with renewable crushed limestone

becoming neutralized thus avoiding chemical treatment or dilution using substantial quantities of tap water. To obtain

a Condensate Neutralization System, please contact your local PVI representative.

1. Follow the steps 1 through 4 in the Condensate Drain, Trap & Disposal section above.

2. Locate the Condensate Neutralization System in the condensate piping, as shown in the FIELD INSTALLED

CONDENSATE DIAGRAM above.

3. Position with removable crushed limestone fill-cap in vertical position only. The bottom of the condensate

neutralization system outlet pipe must not be higher than the bottom of the water heater.

4. For proper operation, the water heater condensate outlet must be plumbed with CPVC plastic pipe to the lowest

fitting of the Condensate Neutralization System, connecting to the “INLET” as shown in the graphic below.

5. Keep the Condensate Neutralization System closed at all times, except for maintenance.

Optional Condensate Neutralization System

WARNING: Keep the Condensate Neutralization System closed at all times the appliance is operating. The

system must remain closed to prevent hazardous products combustion from continually enter the room.

Failure to keep the Condensate Neutralization System closed can cause property damage, personal injury,

exposure to hazardous materials or loss of life.

6 GAS SUPPLY AND PIPING

Verify that the type of gas specified on rating plate is supplied to the unit. This unit is orificed for operation up to 2000

feet altitude. Appliance Btuh output derates 4% per 1000 feet elevation above sea level. Consult Factory for

installations above 2000 feet elevation.

6.1 Gas Train and Controls Certification

NOTE: The gas train and controls assembly provided on this unit have been tested under the applicable American

National Standard to comply with safety and performance criteria such as proper ignition, combustion and safety

shutdown operation.

6.2 Gas Control Trains

All models include gas control trains with the following components: main manual shutoff valve, two safety shutoff

valves, proportionator regulator and a final manual valve with the manifold pressure tap on the side of the valve.

These components may be separate or two or more may be combined in a common housing.

CAUTION: Do not adjust or remove any screws or bolts on gas train control components which are sealed

with a red or blue colored compound. Doing so will void all approvals and warranties.
