NOTICE
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
FLO-RITE-TEMP
INSTANTANEOUS WATER HEATER
INSTALLATION AND ADJUSTMENT INSTRUCTIONS
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.
STEAM SIDE INSTALLATION
(Refer to Fig. 2-1)
1. 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.
2. 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.
3. An Armstrong Y-strainer should be installed before the pressure reducing valve to reduce the chance of dirt
fouling.
