INSTALLATION AND ADJUSTMENT INSTRUCTIONS

No water heater will work satisfactorily if improperly installed and operated. These instructions contain

important information for the installation and adjustment of the FLO-RITE-TEMP Water Heaters. Read

these instructions carefully before installing this unit. FAILURE TO ADHERE TO THESE

INSTRUCTIONS COULD RESULT IN SERIOUS BODILY INJURY OR PROPERTY DAMAGE.

STEAM PIPING INSTALLATION OF A SINGLE UNIT

Single and Double Wall

NOTE: FLO-RITE TEMP is provided with (1) one Armstrong Steam Trap and Thermostatic

Air Vent (shaded). All other items shown not included.

NOTE: units may be piped in parallel for larger capacity requirements. See Fig. 15-1 for an example of

parallel unit installation.

The unit includes the mixing valve mounted to the heat exchanger, channel iron and U-bolts mounted,

thermostatic air vent installed on the heat exchanger, a water pressure pop off valve integral to the unit control

valve and a separate Armstrong Inverted Bucket Steam Trap.

Install the FLO-RITE-TEMP with adequate room to allow for tube bundle removal when cleaning is

required. See Table 12-1 for specific dimensions.

If 2-15 psig of steam is available a pressure reducing valve is NOT required. If a pressure reducing valve is

required, an Armstrong Inverted Bucket Steam Trap is recommended to drain condensate at the inlet of the

pressure reducing valve.
