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 so the installation conforms to the National Fuel Gas
Code, ANSI Z223.1. When resizing any portion of the common venting system, the common venting system should be resized to
approach the minimum size as determined using the appropriate tables in Appendix G in the National Fuel Gas Code, ANSI Z 223.1.
H. UNCRATING THE HEATER
UNCRATING HEATER – Any claims for damage or shortage in shipment must be filed immediately against the transportation company
by the consignee.
Cold weather handling – If heater has been stored in a very cold location (below 0 o
F) before installation, handle with care until the
plastic components come to room temperature.
Remove all sides of the shipping crate to allow the heater to be lifted into its installation location. The heater is also equipped with
leveling feet that can be used to level the heater properly on an uneven location surface. If surface flooring is rough, take care when
sliding heater into position, as you could catch the leveling feet and damage the heater.
PART 4 – HEATER PIPING
Failure to follow the instructions in this section WILL VOID the warranty and may result in property damage, serious injury, or death.
DO NOT pipe this water heater with black iron, galvanized steel, steel, or lead pipe. Doing so will result in premature product failure and
property damage, and WILL VOID the product warranty.
Plumbing of this product should only be done by a qualified, licensed plumber in accordance with all local plumbing codes. The heater
is designed to be connected to a storage tank to supply domestic hot water. HTP offers 60/80/119/175 gallon size storage tanks in
either stainless steel or glass-lined construction. These storage tanks will be directly connected to the heater supply and return
connection.
A. GENERAL PIPING INFORMATION
The building piping system must meet or exceed the piping requirements in this manual.
Use two wrenches when tightening water piping at the heater. Use one wrench to prevent the heater return or supply line from turning.
Failure to prevent piping connections from turning could cause damage to heater components.
NOTE: The addition of a high temperature limiting device is important if the heater is to be connected to a domestic hot water system.
Connect the cold water supply to both the storage bottom port and the supply side of the heater (shown in Piping Details, Section J). It
is important that you install a flow check on the supply line of the heater BEFORE connecting the feed line to the storage tank. This
Never use dielectric unions or galvanized steel fittings when connecting to a stainless steel storage tank or heater. Failure to follow this
instruction can lead to premature failure of the heater system. Such failures ARE NOT covered by warranty.
