BEFORE YOU START

 

This manual covers the application, installation, operation and 

maintenance of a Futera III Series finned copper heating boiler/

water heater/pool heater (Canada only). To obtain the safe, 

dependable, efficient operation and long life for which this heating 

boiler/water heater was designed, these instructions must be read, 

understood and followed.

The Futera III Series finned copper heating boiler/water heaters 

have been design certified by CSA for use with natural and propane 

gas under the latest revision of ANSI-Z21.10.3/CSA 4.3, Gas Water 

Heaters, ANSI-Z21.13/CSA 4.9, Gas-Fired Low Pressure Steam 

and Hot Water Boilers ANSI-Z21.56/CSA 4.7 Gas-Fired Pool 

Heaters (Canada only) and CAN1-3.1, Industrial and Commercial 

Gas Fired Packaged Boilers. Each unit has been constructed and 

hydrostatically tested for a maximum working pressure of 

160 psi

1103 kPa

 in accordance with Section IV of the A.S.M.E. Boiler 

and Pressure Vessel Code.
