it only with an identical gas control valve model. Ne sure the part number is the same.
• The heater’s access side panels must be in place to provide proper ventilation and to avoid water intrusion.
Do not operate the heater for more than ve (5) minutes with the side panels removed.
• This heater is certied by CSA International as complying with the Standard for Gas Fired Pool Heaters,

Heater Identification Information (HIN)
To identify the heater, see rating plate on the inner front panel of the heater. There are two designators for each
heater, one is the Model Number and the other is the Heater Identication Number (HIN).
Heater Identification Number (HIN)
The following example simplifies the identification system:
1) ETi
2) Model Size : (250) : Input rating (Btu/hr)
X 1000
3) Fuel Type : NA = Natural gas
4) Construction : ASME = Commercial Model
