Marley Engineered Product M series radiant heaters can be field modified by adding optional kits. Refer to Figure 3 to select the proper kit.
Portable Cart Kit
The portable cart kit can be used to convert a fixed overhead unit into a portable heating device where a fixed installation is not required. This kit includes wheels, legs, handle, grill(s), baffle (if req'd) and all of the necessary hardware to complete the modification. See instruction sheet
“CAUTION - Use of this kit presents certain hazards including risks for fire or burns. Extreme care must be taken when use of any Marley Engineered Products heater with this kit. See Warnings in front of this manual for additional details. As an added safety precaution, we strongly recom- mend the Tip Over Kit and Grille Kit be used in conjunction with the Portable Cart Kit. It will help reduce the risk of fire if the heater and cart happen to fall over or if something hap- pens to fall against the heater.”

ELECTRIC SHOCK HAZARD. Disconnect all power before servicing or replacing heating elements.
The heater requires no special maintenance other than occa- sional cleaning to prevent excess accumulation of dust and lint on surfaces. It is important for the reflectors to be kept clean to obtain the maximum radiant output. If used as a movable unit, the cart and cord should be checked periodically to make sure the hardware remains tight and cart and cord are not damaged. Do not continue to use the heater if damaged.
Element Replacement
1.Remove Terminal Box Cover.
2.Disconnect lead wires from heater terminals.
3.Remove safety grills (if installed).
4.Remove retainer screw located on the reflector at the terminal end.
5.Loosen (2), 3/8" nuts from the terminal box bracket located on the back of the heater and slide the entire heating element assembly out of the reflector assembly.
6.Remove wires and jumper straps as required to replace the failed heating element(s).
7.Remove bulkhead fitting nuts and washers.
8.Remove failed element and replace with a new element. Replace only with genuine Chromalox "Arctic End" elements. Use of other elements will cause excess temperatures inside terminal box.

10.Place washers and nuts on bulkhead fittings and tighten.
11.Replace wiring and jumper straps.
