Pipe Mounting Kit for use w/Ruffneck™ FX Series Heaters (FX5/FX6) 20" Frame

Description

Pipe Mounting Kit (PMK) 20" Frame
-
Particularly useful in buildings with insufficient structural strength to use other types of mounts. Requires 3" (76 mm) pipe (3½” / 89 mm O.D.) (not supplied).
Mounting kits are made of steel with wet-applied enamel paint. If the heater is installed on a structure that is to be transported, provide additional support for the heater during transit. The suspended weight should not exceed 300 lbs (136 kg). *Not suitable for models ‑ HP 30, FR 30, HP 36, FR 36, or Tandem AH Series (24B fan configuration)
Although Ruffneck™ Unit Heaters are designed to be installed in an upright and level position, they may be installed in other positions. However, for steam service, the inlet must be above the outlet and the bottom of the core must drain toward the outlet. They are designed to be suspended from the top of the cabinet either with two or four (depending on model) 5/8" NC bolts screwed into internally threaded holes provided in the cabinet top panel. It is essential that adequate structural support be provided for installation.
Basic Mounting Kits (BMK), Hanging Mounting Kits (HMK), Swivel Hanging Mounting Kits (SHMK), or Wall Mounting Kits (WMK) are available for Ruffneck™ heaters. If the strength of the structure is not adequate to support the units, a suitable alternative such as the Ruffneck™ Pipe Mounting Kit (PMK) would be recommended to ensure safe and proper operation. The HMK is the only suitable mounting kit for the 30" and 36" heater models.
Where heaters are installed in applications that are of a relocating or transportable nature such as land or offshore drilling rigs, an adequate mounting structure should be supplied to withstand all probable load conditions. Such load conditions should recognize abuse situations such as truck offloading impacts, etc. It is recommended that lock washers be
used beneath the bolt heads for these installations.
Heaters may be mounted at any reasonable height above floor level depending on the purpose of the heater. When equipment is placed in a seldom occupied building, the heaters may be placed at a low level. When heaters are required to ensure personnel comfort, they should be mounted overhead. Typical mounting heights range from 7.5 ft to 12 ft. CSA-certified heaters must be mounted at a minimum height of 7.9 ft (2.4 m) above the floor. All Ruffneck™ heaters have louvers installed that allows airflow to be directed from horizontal to 60° or greater downward deflection. Louvers should never be set to within less than 15° of the closed position.
Clearances for Maintenance
- It is important to provide adequate clearance around the heater for servicing. Allow enough space to permit easy fan or motor replacement. Do not position the back of the fan motor against a surface, as air for the cooling fan will be blocked. It is advisable to leave at least 2" of clearance between the rear of the motor and the nearest obstruction. For easy removal of the heat exchanger core assembly, it is important to leave clearance beneath the heater equal to the height of the heater cabinet plus an additional
2 inches.
