The LMD Boiler is your answer to costly and
ineffective ELECTRIC HEAT. With its compact design, the LMD can be installed
in a space as small as a closet.


 
 | Direct vent oil fired hot
water boilers, Model Nos. LMD-75, LMD-100 and LMD-110 are approved for
horizontal thru the wall venting.
|
 | Featuring minimum clearance
to combustibles - sides 2", rear 2", front 12", chimney connector 9"
|
 | Suitable for closet or alcove
installation and for installation on combustible flooring
|
 | No chimney or power vent
required - The LMD can be vented up to 20 feet horizontally without a
power vent, making the installation and maintenance of the boiler easier
and less costly
|
 | Prepurge and postpurge
control - Prepurge is provided to assure clean starts and is
accomplished through the use of a delayed oil valve. The postpurge timer
is supplied to cool the combustion head and eliminate combustion gases
from the venting system producing clean, efficient boiler operation
|
 | Flexible Stainless Steel Vent
Kit - The vent kit is available in three lengths: 10, 15, and 20 foot
lengths of five inch flexible stainless steel pipe and a stainless vent
termination end. The kit also provides the parts necessary for
combustion air intake. Available in a combination vent or standard
intake and exhaust vents
|
 | Water Volume - The low 5-1/2
gallon water content provides heat and hot water delivery within minutes
of start up. The low mass concept reduces standby losses associated with
boilers during the off cycles and provides nearly instant heating with
less full consumption.
|
 | Efficiency - 83% to 85% AFUE
- The high efficiency obtained with the LM Boiler are due to the design
of the heat exchanger and the reduction of standby losses.
|
 | Multiple Firing Rates - .75
to 1.10 - One boiler can be fired at three different firing rates,
offering versatility and lower cost maintenance. Each unit is supplied
with three nozzles for three firing rates.
|
 | Compact Size - Standing
19-3/4 inches high, 19 inches wide, and 36 inches long, this compact
boiler not only saves space, but can easily be installed in areas not
approved for other boilers. The boiler can be easily cleaned from the
front or the back.
|
 | ASME Constructed and IBR
Rated - Each boiler is constructed and hydrostatically tested in
accordance with ASME boiler code. The capacity and efficiency are rated
in accordance with the standards of the Institute of Boiler and Radiator
Manufacturers (IBR).
|
 |
Lifetime Limited Warranty - Unlike
other pro-rated warranties that often cover a small percentage of the
cost of a new boiler after the 15th or 20th year, Thermo-Dynamics boiler
replacement costs are never more than 50% of the replacement boiler list
price.
|
 | Built in "Air Scoop" purges
air from the system providing a quiet, trouble free hot water heating
system without the use of external devices.
|
 | Weld fittings extend beyond
the jacket and allow the service technician or homeowner to see small
leaks that, if undetected could later damage the boiler shell and
potentially void the warranty.
|
 | Easy cleaning and maintenance
accessibility to the combustion areas and the open tubes make it easy
for the service technician to thoroughly clean the boiler. The LMD
series can be cleaned from either end by simply removing eight brass
nuts. The burner end clean-out door is a
hinged, swing-away door. A well- maintained boiler continues
to perform at a higher efficiency and is less likely to develop service
problems.
