manual abstract
Your Drolet insert will attain its best performance if installed with a chimney that generates its own draft. The minimum requirement of a flue will be the installation of a flue connector (the liner must conform to UL1777 chimney liners) from the insert into the first flue tile of the chimney (USA), see Figure 2.3 , or a continuous stainless steel liner (the liner must conform to the Class 3 requirements of CAN/ULC-S635) directly connected to the flue outlet (Canada), see Figure 2.2. A continuous 6" (152mm) stainless steel liner from the top of the chimney is the optimum system and will provide the best performance, as well as compensate for poor draft situations caused by large cross-sectional chimneys. The insert will not work without a positive seal in the chimney. Chimneys constructed outside of the home, on an exterior wall, should be avoided if possible, especially in colder climates. Outside chimneys may not draw as well and may downdraft due to the difficulty in heating them up to operating temperature. Cooler chimneys will result in increased creosoteing, less draft, and poorer performance. Draft is proportional to overall chimney height as well as to stack temperature. Draft can be increased by increasing chimney height, and by reducing heat loss from the chimney through an insulated liner. Ensure that all joints in the flue systems are tightly sealed, since any leaks will result in reduced performance as well as a possible safety hazard. 5 Section 2.0 Installation 2.1 Clearances To Combustibles (Measured From Insert Body) Sidewall (A) Escape 1400-I 13” (330 mm) Shelf (B) 22” (559 mm) Side mantle (C) 10” (254 mm) Top mantel (D) 29” (737 mm) Table 2.1 CLEARANCES Figure 2.1 Note: If side mantle protrudes more than 1.5” (38mm) in front of face of fireplace, then use sidewall clearance. 6 2.1.1 Hearth Requirements If the non-combustible hearth is flush with the floor, then the hearth must be 16”/406mm (18”/450mm in Canada) in front of the fan housing (see Figure 2.1.2). If the noncombustible hearth is a minimum of 4” (102mm) above the floor, then the hearth can be 6” (152mm) out from the fan housing with a 10” (254mm) floor protection (sparks) extended beyond the hearth (see Figure 2.1.1). The non-combustible hearth must be a minimum of 8” (203mm) on each side of the unit (Canada & USA). Convert specification to R-value: k-factor is given with a required thickness (T) in inches: R=1/k x T C-factor is given: R=1/C Example: If the floor protector is 4” brick with a C-factor of 1.25 over 1/8” mineral board with a k factor of 0.29 the total R-value of the system is: 4” brick C=1.25, R=1/1.25=0.8 1/8” mineral board K=0.29, R=1/0.29 x 0.125=0.431 Total R = Rbrick + Rmineral = 0.8 + 0.431 = 1.231 Total R is greater than 1.0, the system is acceptable.

It is important to follow the installation and operation instructions. An improperly installed or operated insert could result in a safety hazard or fire, or damage to the unit, which would not be covered by the warranty. Contact local building or fire officials about restrictions and installation requirements in your area. You should be familiar with the installation and be sure that the work is done in accordance with this manual. WARNING: DO NOT INSTALL THIS INSERT IN A SLEEPING ROOM. 2. Where lesser clearances are desired, consult your local authority as regulations may vary regarding the use of clearance reducing devices. Listed wall and floor shields are available to reduce clearances, and most building codes provide information on materials which may be used to reduce clearances. 3. Maintain at least the minimum clearances to combustible material as specified in this manual. Clearances are measured to the nearest part of the insert (i.e. top edge on the side). Clearances to any combustibles, when measured directly out from the front, must be a minimum of 48" (1219mm). 4. Maintain at least the minimum floor protection for combustible floor materials as specified in this manual. Floor protection to the front is to be measured from the fuel loading door opening. 5. Drolet recommends that you install a listed smoke detector or alarm in your home. Normal operation of the insert will have no effect on the detector or alarm. 6. The insert is to be connected only to a lined masonry chimney and masonry fireplace conforming to building codes for use with solid fuel. Do not remove bricks or mortar from the existing fireplace when installing the insert. This insert must be connected to a code-approved masonry chimney or listed factory-built fireplace chimney with a direct flue connector into the first chimney liner ...
