Mr. Heater | Gas-Fired infra-Red tank top Heater

1.  Heater model MH15tS and MH30tS are packaged 
 

complete. Propane cylinders (tanks) are not included 
with heater model. 

2.  Remove heater from carton. 
3.  use only vapor withdrawal lP gas cylinders constructed 

for use with propane only (HD-5) and marked in accor-
dance with the specifications for lP gas cylinders of the 
u.S. Department of transportation (Dot SPeC. 39). 

4.  this heater must be used only with a vapor withdrawal 

lP gas bulk tank equipped with a standard Pol valve 
– do not use this heater on bulk tanks greater than 20 
pounds lPG capacity (50 pounds water capacity).

•  the tank collar bracket must be assembled before 

the heater can be attached to the propane tank.

•  Remove screws holding Piezo igniter bracket to 
 

manifold center plate and retain for later use.

•  Align bolt holes in tank collar bracket with bolt 

holes in center plate on manifold such that the 
heater is facing outward once attached to cylinder 
collar.

•  Attached with screws removed above, making sure 

that Piezo igniter bracket is between tank collar 
bracket and manifold center plate.

•  Place heater onto tank with tank collar bracket over 

tank collar. Mounting bolt knob should be posi-
tioned to the outside of tank collar.

•  Firmly secure to tank by hand-tightening mounting 

bolt knob. Do not overtighten.

•  Make sure heater regulator is in the “oFF” position.
•  insert regulator’s connector into tank’s valve and 

turn left (counterclock-wise) with hand as much as 
possible. Do not overtighten.

•  Be sure heater is facing away from tank. 
•  insert regulator connector into tank valve outlet 

fitting and turn left (counterclock-wise) until fully 
tightened. Do not overtighten. (See Figure 2a)

•   Place heater support around venturi and slide clip 

ends onto propane cylinder collar.  use 1/4”-20 x 
35mm screw and wing nut to secure heater sup-
port onto venturi tube. (See Figure 2b)

Figure 2a.

6.  operate only on a stable, level surface. 
7.  open propane tank valve slowly.
8.  Check all fittings for leaks. Apply a 50/50 mixture of 

liquid soap and water to all joints. Bubbles forming 
indicate a leaking connection. Correct all leaks before 
proceeding.

  never touch heater while in operation to avoid injury. 

Move heater by grasping the propane cylinder carefully. 

9.   the heater should be inspected before each use and at 

least annually by a qualified service person.

10. the hose assembly shall be visually inspected prior to 

use of heater.  if it is evident there is excessive abrasion 
or wear, or the hose is cut, it must be replaced prior to 
the heater being put into operation. Replacement hose 
assembly shall be Mr. Heater hose assembly as listed in 
the parts list.

11.  Minimum inlet gas pressure is 20 psi.
12.  Maximum inlet gas pressure is 120 psi (equivalent to an 

ambient temperature of 75

°F (24°C)).
