Trane Gas Unit Heaters Katalog

58

 UH-PRC002-EN

Unit is completely factory assembled, piped, wired and test fired. Unit is AGA and CGA certified, 
over 80 percent thermal (combustion) efficient. These propeller type units are provided with 
aluminized tubular heat exchanger, in-shot burner, hot surface pilot ignition, individually 
adjustable and removable louvers, 100 percent baked enamel finish, 115/60/1 supply voltage, 
removable access door on size 30 to 120 MBh, and hinged access control panel on 150 to 400 MBh, 
power vented, single-stage combination gas valve, two-stage available on 150 to 400 MBh, 24V 
control transformer and 115/60/1 volt fan motor with internal overload protection. The size 30 to 
120 MBh are available in low profile design. OSHA fan guard is standard on all units size 30 to 
120 MBh. Units sized 150 to 400 MBh are shipped with a non-OSHA type guard; the OSHA guard 
is available as a selectable option.

Heat exchanger construction consists of 20-gauge aluminized steel. The tubular design provides 
maximum and uniform heat transfer. The low pressure drop enables heated air to be evenly 
distributed. The curved, non-welded serpentine design, experiences less thermally induced stress 
making it highly durable for longer service life.

The cabinet is constructed of 20-gauge cold rolled steel. All components are individually 
electrostatically painted.

This ignition is constructed of shock resistant ceramic composite hot surface element. This system 
does not permit pilot gas to flow unless the hot surface element is present and powered. The low 
voltage hot surface element lights the pilot quickly for fast heat delivery. All wiring is 24V with no 
line voltage in the burner area.

The tubular design is AGA/CGA certified in accordance with Categories I and III venting 
requirements. Category I enables units to be vented vertically with either single or double wall 
venting material. Category III allows for horizontal venting utilizing single wall venting material. 
This venting flexibility makes installation easier and more cost effective.

All controls are easily accessible with ignition and fan controls located in one centrally located 
control panel. The removable door on size 30 to 75 MBh and the hinged access door on the 100 to 
400 MBh provide control isolation.

Motor is 115V, 60 Hz, single phase, open drip-proof with built-in thermal overload protection.

Motor — 115V totally enclosed. Motor is 115V, 60 Hz, single phase, totally enclosed with built-in 
thermal overload protection.

The heat exchanger, flue collector and burners are covered by a 10-year warranty from the date of 
manufacture.
