Statement of Intended Use:

The Mason-Lite Masonry Fireplace is a modular refractory masonry unit designed for ﬁ eld assembly. The ﬁ rebox is constructed using pre-cast, interlocking refractory blocks. The blocks are then secured to each other using Mortar. The system includes all parts necessary for the assembly of a complete masonry ﬁ replace. In addition to the basic enclosure, a standard 1-1/8” thick, high temperature refractory brick is required to line the interior of the ﬁ rebox and can be purchased from the manufacturer.

It is the responsibility of the distributor, subcontractor and/or the general contractor – whoever shoulders the liability for installation of this product – to see to it that the work is in complete compliance with the guidelines and instructions in this manual. Note that the general contractor is the party accountable for seeing that adequate clearances are provided from all ﬁ rebox surfaces per speciﬁ cations in this manual.

DO NOT USE A FIREPLACE INSERT OR OTHER PRODUCTS NOT SPECIFIED FOR USE WITH THIS FIREPLACE.

These ﬁ replaces are not intended to serve as a primary heat source, rather, the ﬁ replace was expressly created as a supplemental source of heat. The unit is designed for use with solid fuels such as cord wood.

WARNING:

Any application other than the “Intended Use” as stated above is in violation of the manufacturer’s instructions and is hereby prohibited. Such violation may cause immediate hazard, property damage or loss of life and will void all liabilities to the manufacturer and will void all warranties explicit or implied.

Product Overview

Introduction

We extend a warm welcome from all of us at Masonry Fireplace Industries, LLC. (MFI), proud manufacturers of Mason-Lite Fireplaces. Thank you for Choosing MFI. You may have thought long and hard before you chose the ﬁ replace which would grace your home. Rest assured that every component of the Fireplace has been tested to ensure long-term durability.

Product Overview

Mason-Lite Fireplaces are designed as factory-built blocks to be assembled on-site. These ﬁ replaces may be installed on either combustible or non-combustible ﬂ oors. In order for the ﬁ replace to be installed on a combustible ﬂ oor though, it is necessary that the ﬁ replace be supported on a platform or sub-ﬂ oor that is non-combustible.

The Four Components of the Mason-Lite Fireplace:

Combustible or Non-Combustible Floor

•

Non-Combustible Raised Platform

•

MASON-LITE Firebox and Smoke Dome

•

UL103 class A listed chimney system required.

Important: Follow the chimney pipe manufacturer’s

instructions on the installation of their speciﬁ c ﬂ ue system.

Note that each of these topics will be covered in detail and that the installer is expected to understand each phase completely before going on to subsequent instructions.

Attention: Be advised that all the illustrations in this manual

are for general reference only. Do not scale drawings. Actual design elements will vary from case to case. Pay attention to speciﬁ ed minimum clearances to combustibles.

Testing and listing for these Mason-Lite Fireplaces has been undertaken by PFS, Inc.

Corner Installation

Flush

Installation

Careful step-by-step instructions for each phase of the installation procedure will be given for the Mason-Lite conventional radiant heat ﬁ replaces. Those instructions generally fall into the following categories:

•

Spacing and clearance as it relates to combustible materials.

•

Familiarity of installation for all components.

•

The strength of the ﬂ oor on which it rests.

Chimney system measurements.

•

Choice of materials and craftsmanship in ﬁ replace and

•

hearth ﬁ nishing.

Attention: You may need a residential building permit to install

a Mason-Lite Fireplace. Consult local jurisdictions before you get started!

If asked, advise the local authorities that the Mason-Lite Fireplace is designed for installation per the National Fire Protection Association Standard for Chimneys, Fireplaces, Vents and Solid Fuel-Burning Appliances (NFPA211).

When choosing the location of your Mason-Lite Fireplace, keep in mind you must maintain 2” (two inches) minimum clearance from left, right and rear of Fireplace to surrounding structure. Also, when choosing a location, consider outside air requirements to determine if it will be on the left or right side of the Fireplace. In the case of an island installation, outside air accessibility may be obtained through sub ﬂ ooring. See section on Installing Outside Air on page 28.

Clearances to Combustibles

The distance to be maintained from the surfaces of the ﬁ replace to combustibles must be observed. Below is a list of the most common combustible materials to name a few:

Drywall Wood ﬂ ooring Plywood Sub-ﬂ ooring Wood Framing Particle board Mill board Plywood paneling

Maintain the following clearances:

Unit sides, rear, Dome sides, rear & top: 2” (51 mm)

•

Combustible Floors (MFP-33,39,44,49): 6” (152 mm)

•

Combustible Floors (MFP-63 only): 8” (203 mm)

•

Combustible Sheathing above opening top: 18” (203 mm)

•

Sheathing or trim to opening sides: 8” (203 mm)

•

Figure 17

Understanding Clearance to Combustibles

There is a build-up of a considerable amount of radiant heat on the outer surfaces of the Mason-Lite Fireplace. It’s critical that proper clearances to combustibles be maintained so that this radiant heat is maintained to safe limits.

Mason-Lite Fireplace & Chimney System

The Mason-Lite is designed to be installed with a listed UL103 - Class A, Metal Chimney System.

This Mason-Lite ﬁ replace is intended as a supplemental heat source only. It is not intended as a primary heat source.

It is the responsibility of the contractor installer (not the manufacturer) to ensure that adequate combustion air is provided for proper function of this ﬁ replace. Fireplaces take up a large volume of replacement air from outside the house and if the house is of airtight construction, smoke spillage may occur if proper draft is not achieved.

There are many conditions beyond the manufacturer’s control regarding improper ﬁ replace operation. The manufacturer cannot ensure “smoke free” operation, nor can the manufacturer take on the responsibility for problems with surrounding construction; chimneys that have not been built at the correct heights; system drafts caused by faulty mechanical systems; adverse weather conditions or any other environmental situations over which the manufacturer has no control.

Inspect all ﬁ replace & chimney components for evidence of damage prior to starting installation. Consult your local distributor for replacement parts if necessary.

Under no circumstances should you make any adjustments or modiﬁ cations to the chimney system during the installation procedure. If you do, you are not only liable for negating the warranty, but you could very well cause a serious malfunction of the ﬁ replace. You must follow these chimney instructions.

Caution is urged if it is decided to add insulation material to any part of the Mason-Lite Fireplace or Chimney system, be certain that the insulation material is kept at least 2” (two inches) away from any part of the system. When using insulation or vapor barrier materials, cover with a layer of plywood, particle board or gypsum board to maintain the speciﬁ ed 2” (two inch) clearance.

Air spaces around ﬁ rebox must remain open. DO NOT ﬁ ll these open spaces with insulation or packing material of any kind.

Chimney System Heights

Combustible Floor Clearances

These Mason-Lite Fireplaces have been designed with clearance to combustible ﬂ oors as indicated in Page 18. Cover any part of the combustible ﬂ oor system left exposed with 1” (one inch) thick ceramic ﬁ ber insulation rated up to 2,100° F.

Attention: It is critical to abide by the clearances listed in this

manual for all components speciﬁ ed as it allows for movement of hot air from the fireplace into interior areas of the chimney chase. Also, be certain that the chimney system be installed as stated below. Prior to starting the installation, check with

local, regional or state codes for any restrictions or required permits regarding your ﬁ replace installation.

When installed, the maximum overall height of the chimney

system from bottom of ﬁ replace to the top/termination chimney

is 40 feet. The minimum installed height of the completed

Chimney System is 14 feet with a straight ﬂ ue stack, 17 feet if the chimney includes one or two offset sections.

Supporting Floor Systems

It is the ultimate responsibility of the installer to ensure that proper concrete slab supports are used.

WARNING to the licensed design professional and/or building

contractor: It is your responsibility to be certain that the Mason-Lite can be properly supported by the combustible ﬂ oor system on which the ﬁ replace will rest.

For ﬁ replace support foundations installed on concrete refer to

Appendix I and II (pages 31 & 32) for speciﬁ c instructions.

Attach the ﬁ rebox side wall anchors to steel support frame by inserting all-thread rods through holes on the bottom ﬂ ange on the steel support frame as shown in Figure 24 and 25. Secure with two Ø 2” o.d. x Ø 9/16” i.d. x 0.10” Washers and two 1/2”-13 UNC Nuts.

Rebar locations

Lay-out the position of the ﬁ replace and drill holes where the rebar will be located. Secure the #3 rebar 4 inches into the concrete foundation with ITW Epoxy or Simpson Epoxy. Follow manufacturer’s instructions for installation of rebar into slab.

Wood Floor

Anchorage of ﬁ replace to wood ﬂ oor construction is required.

Refer to Figure 21 for anchorage dimensions. Four anchors

are required to attach to the sub-ﬂ ooring framing.

Crawl Space or Upper Floor:

For installation of ﬁ rebox over combustible crawl spaces or upper ﬂ oors, anchorage of the ﬁ rebox is required. Illustrations of examples of possible anchorage methods are shown in Figures 18 thru 20 depending upon the type of ﬂ oor framing. Final method of anchorage is to be determined by licensed design professional.

For conventional framing, where the ﬂ oor joists are parallel with the sides of the ﬁ rebox, the addition of ﬂ oor joists to align with the anchor brackets allows the brackets to be directly connected to the ﬂ oor joists.

Note that additional ﬂ oor joists may be required to support the weight of the ﬁ rebox and chimney. Where the ﬂ oor joists run parallel to the front of the ﬁ rebox, anchorage can be accomplished in like manner as shown in Figure 18 using blocking between the ﬂ oor joist.

I-Joist Anchoring Top View

For ﬂ oors supported by I-Joists, the method of anchorage is illustrated in Figures 19 and 20. Figure 23 illustrates the general arrangement of anchorage to ﬂ oor framing.

It is important to take into consideration that the load for the Mason-Lite Fireplace must be considered as additional dead load that will have to be supported by the ﬂ oor framing. Additional ﬂ oor joists or I-joists may be required as determined by the licensed design professional.

The dead weights for the ﬁ replace are noted in Table I. It is the task and responsibility of the general contractor/installer to see that the proper reinforcement for weight loads are made by a licensed design professional prior to the ﬁ replace installation.

As stated above, it is desirable to place additional framing for alignment of anchor rods. Refer to Figure 21 for anchor rod locations.

What You Will Need

You will ﬁ nd that the MASON-LITE Fireplace is designed to be completely assembled on-site, consisting of interlocking precast parts. You will need a thin-set type mortar for bonding. The parts of the ﬁ replace are made of Mason-Lite’s incredibly strong blend of specialty cement and a light weight aggregate.

IMPORTANT! When applying mortar, it is imperative that the concrete blocks be maintained moist (not soaking) so they don’t absorb the water out of the mortar and cause adhesion to fail. Frequently run a damp sponge to the parts before mortar is applied!

The installation of an anchor plate/damper is required but not supplied. You may purchase it from any chimney manufacturer or MFI. Also, an optional combustion air inlet MFP4-AK can be obtained from MFI. Refractory Firebrick Liners also need to be installed. These should be a minimum of 1-1/8” (one and one-eight inches) thick. The liner will be applied within the walls and hearth area of the ﬁ rebox. These are available from MFI. See page 27.

Field Assembly Procedures

Mixing the MASON-LITE mortar – The mortar comes

premixed and should be dry. Be sure to use clean water and work it up into a mixture that is pasty but not lumpy. If it’s too thin and the surfaces don’t stay moist, the components will not adhere. Load the mixture into a standard grout bag.

Apply about ½” (one-half inch) thread of mortar. The mortar

bead should be approximately ½” (one-half inch) away from all edges. The mortar has a considerable amount of holding power so do not overload the components with too much mortar. Keep the components moist at all times!

Some mortar will “ooze out” when placing components

together, this is normal. Wipe excess away with a trowel. Do not cover component surfaces completely with mortar. Do not apply the mortar in thick bands even if the component you are working with is larger than the rest. You will want to apply “stripes” of mortar in these situations.

Make sure components are level. It’s extremely important

that you pay careful attention to how you are assembling the Mason-Lite Fireplace since every component builds on the next. If you have to make any kind of an adjustment, do not try to do it “by loading an opening” with mortar, this will only result in a ﬁ replace that will not be plumb or level.

Use wood shims instead. You will ﬁ nd these small wood shims supplied with the Mason-Lite Fireplace and

you can nudge them in between openings to achieve the precision you need in making component adjustments. Once you have removed any shims, you will want to cover any gaps that may have resulted with the mortar.

Attention: Clearance to combustible construction cannot be

reduced during course of construction. For the safe operation of the ﬁ nished ﬁ replace, these clearances must be followed when building the framework for the chimney system.

Note that the most important aspect of the installation is maintaining the minimum required clearances to combustible materials according to the chimney pipe manufacturer’s recommendations, otherwise a potential ﬁ re hazard may occur.

Warning: do not interchange chimney manufacturer’s parts

with any other parts except those speciﬁ cally required by the chimney manufacturer’s recommendations otherwise a potential hazardous condition may be created.

Attention: When choosing a Chimney System it must meet

the following requirements:

Designed for installation in accordance with the National Fire Protection Standard and UL 103.

Meets the requirements of NFPA 211.

Designed in accordance with ICC Codes.

Assuming you have sections of vertical pipe that are more than 10’ (ten feet) measuring between elbows, you must insert – at midpoint – a chimney stabilizer. When installing the stabilizer, pull out the support straps with a good amount of tension and hammer to the frame.

Mason-Lite Firebrick Liners

Custom Firebrick Lining

Custom Firebrick lining is not supplied by Masonry Fireplace

•

Industries (MFI). There is, however, the option of modular

pre-fabricated panels that can be obtained from MFI. See exploded parts page for details.

•

If a custom ﬁ rebrick pattern is desired, it is required that the brick be at least 1-1/8” inch. The pattern for the ﬁ rebrick lining is exclusively your choice. Before you install the lining, remember to consider any holes your contractor may need to drill for gas, electrical or combustion air kit access holes.

Please use a certiﬁ ed mason to lay-in the brick. He will follow

•

the proper instructions from the ﬁ replace liner manufacturer and also understand the type of adhesive or cement he is to use.

The following Firebrick Patterns are available from MFI:

Fireplace Finishes & Combustible Trim

Clearances

Hearth Material & Dimensions – Strict codes control

the types of materials that you can select for your Mason-Lite Fireplace’s hearth as well as the hearth’s length and width. All hearth extensions must be made of code-rated, noncombustible materials such as tile, brick, concrete or stone.

As with any radiant heat ﬁ replace, all MASON-LITE Fireplaces must comply with building code safety clearances, per units that have openings of 6 sq. ft. (six square feet) or

greater. For Mantel clearances see Figure 17. Walls that

Adjoin – Safety codes and all practical outlooks insist that your ﬁ replace cannot be installed closer than 2 ft. (two feet) to any walls in the room the ﬁ replace is housed in or to any walls of adjoining rooms.

Caution in Regards to Combustibles – If any part of the ﬁ replace or objects in the room (curtains, rugs, paint, cushions, etc.) start to show warping or discoloration due to heat from the ﬁ replace, it is time to take immediate action. Do not use the ﬁ replace until you have ﬁ gured out how to address the problem. You are facing a potential ﬁ re hazard. MFI cannot be responsible for the make-up of material on the exterior of the ﬁ replace you have chosen, nor can MFI be held responsible for the materials in a room that may be responding negatively to heat. However, in almost all cases, there is a solution to the problem, either by making adjustments to airﬂ ow or the modiﬁ cations to the room itself.

Installing Outside Air

The Mason-Lite Fireplace needs enough replacement

air to function properly and some local building codes may require outside combustion air to be provided. If no replacement air is provided, improper ﬂ ue drafting may occur, creating negative pressure whereby smoke may enter the home, especially in homes that are very well insulated and tightly sealed. Check local building codes for speciﬁ c requirements.

Install Combustion Air Kit MFP4-AK into the MASONLITE Firebox through the side wall opening provided. A 4” dia. hole will also be required through the ﬁ rebrick side lining (see

Figure 62). The tubing that goes out of the ﬁ rebox wall must

feed into a ﬂ exible metal conduit as the source for outside combustible air. It can go straight out through an outside wall or into a ventilated crawl space. If crawl space is used, check codes for proper termination.

Figure 62

Be sure that you carefully check the source of the outside air before you choose the site for your air intake. You don’t want a place where snow will collect, where bushes or trees will be growing or a location that is too close to any other structure.

Install a screened termination cap to keep out small animals.

Adding a Gas Pipe

Mason-Lite Owner’s Operation & Precautions

You may elect to add a vented decorative gas

appliance (gas log) to your Mason-Lite Fireplace. If so, follow the installation instructions from the Decorative Gas Appliance manufacturer. Familiarize yourself with requirements for installation as outlined by the National Fuel Gas Code, ANSI Z223.1. This gas pipe provision should only be used on a decorative gas appliance.

You can route the gas piping practically anywhere in the ﬁ rebox – the ﬂ oor, back wall or side walls. You will just need a masonry drill; the instructions from the gas appliance manufacturer will be very straightforward.

Fill in the holes you have drilled around the gas piping with the regular MASON-LITE mortar.

Follow the Gas Log manufacturer’s instructions.

Adding Electrical Connections

Like the gas line, electrical feed lines can be run through the ﬂ oor, back wall, or side walls. Follow local building and electrical code requirements.

Fireplace Grates and Screens

To complete your ﬁ replace installation, a ﬁ replace grate will be required for safe operation. The ﬁ replace grate can be obtained from MFI or if choosing an alternate, it must be sized to 50% of the hearth maximum. Additionally. a ﬁ replace screen must be installed for safety.

When ordering, please refer to the parts lists in the beginning of this manual.

Installers of the Mason-Lite are urged to leave the

owner’s manual with the unit after installation is complete.

WARNING: Do not attempt to operate your ﬁ replace without

a ﬁ re safety screen installed.

CAUTION: The manufacturer cautions against using chemical

chimney cleaners. Never use charcoal or coal in the ﬁ replace under any circumstances.

First Lighting of the Mason-Lite – After construction is completed, all elements of the ﬁ replace and chimney system must be completely dry. This means that the unit must stand without any ﬁ ring for a minimum of 28 days. Only after that period of time can a ﬁ rst lighting take place. The ﬁ rst ﬁ re must be small and well-controlled, started with a small amount of kindling. Add no more than eight pounds of wood, preferably small logs not more than 3” (three inches) in diameter. You will probably burn no more than three to four of these small logs. Do not let the ﬁ re burn for more than one hour. After this ﬁ rst lighting – when the ﬁ replace has started to “cure” Do not set another ﬁ re for at least 24 hours.

Second Lighting – Start the ﬁ re slowly and gradually as you did with the ﬁ rst lighting, but this time you can burn up to ten pounds of ﬁ rewood, probably four to ﬁ ve logs that are 3” (three inches) in diameter. With the second lighting you can let the ﬁ re burn two hours – no more.

After First and Second Lighting – When the ﬁ replace has been properly cured with 1st and 2nd lighting, you will be able to add a full fuel load to the MASON-LITE which is about 10 to 15 pounds of ﬁ rewood at any given time. Consider that this typical fuel load is three to four dry hardwood logs that are about 6” (six inches) to 8” (eight inches) in diameter.

Fireplace Door Accessory

IMPORTANT: Only Crown-Breckinridge or McKenziePendelton Doors are approved for use with this ﬁ replace. For installation Instructions, see separate instructions included with doors.

Without a grate for your ﬁ rewood to rest on, you cannot get the air ﬂ ow you need under the ﬁ re which makes for a hotter, more satisfying ﬁ re.

Don’t “over burn” – Always remember, your Mason-Lite Fireplace is an elegant addition to your home. It is not an indoor incinerator! If you start to use the ﬁ replace and begin a routine of “over burning,” you can permanently and unalterably damage the unit. Under no circumstances should you be burning household trash, including chemicals and combustibles, cardboard boxes, your ofﬁ ce papers, scrap lumber or stray branches from your yard, particularly pine.

WARNING: Burning of above mentioned materials will cause

an unsafe condition and will void your warranty!

Starting a Fire and Basic Operation

Before starting a ﬁ re in your ﬁ replace, open the damper to its’ fully open position. Crumple some paper and place it on the log grate. Use some soft, dry wood as kindling and put it on top of the paper. Place some small logs or split logs atop the paper and kindling.

Finish off the fuel load with a couple of hardwood logs or split logs – oak or hickory. Check to see that you’re stacking the logs so that they will fall inside the grate as they burn.

To get the most out of your wood, it is recommended that you let it set and completely dry out for nine months to a year.

When you are satisﬁ ed with the arrangement of your wood load, light the paper which in turn will ignite the kindling, then the softer wood and ﬁ nally, the harder wood logs. As the ﬁ re burns, you can carefully lay additional logs on the ﬂ ame, but make sure you place them gently without forcing them into the opening.

Annual Fireplace Maintenance

Your ﬁ replace and chimney require seasonal and monthly tune-ups”. Like any piece of well-built equipment, the Mason-Lite Fireplace and chimney needs routine maintenance.

The manufacturer recommends that inspection of the ﬁ replace and chimney take place on a monthly basis during the heating season.

Start at the top, looking for birds’ nests, leaves or any other obstructions. Also check the spark arrestor, for creosote or soot build-up. Twice a year, you will want to clean the ﬁ rebox and chimney yourself or hire a professional chimney sweep to do the job for you. If you elect to do it yourself, use a plastic, wood or steel brush for the inside of the chimney.

Good old-fashioned “elbow grease” is enough to remove the extraneous matter from the inside of the ﬁ rebox and chimney. Never use any chemical cleaners as their residue could introduce a ﬁ re hazard after the task is completed.

Outside Inspection – During your once a month inspection of the ﬁ rebox and chimney, make it a point to also check the outside of the chimney, the metal ﬂ ashing and weather seals that surround it. If you ﬁ nd any cracks or openings around screws or nails, seal them to avoid any roof or chimney chase leaks.

SURFACE CRACKS

The MASON-LITE FIREPLACES are manufactured using high quality materials. During the drying process, surface cracking may occur. These small cracks (under 1/16” will not effect the ﬁ replace safety or performance). During the assembly process, ﬁ ll surface cracks with thin-set mortar and brush when drying for a smooth surface ﬁ nish.

Removal of Creosote and Soot Formation – Creosote vapors are known to form in the relatively cool chimney ﬂ ues of slow burning ﬁ res, hence, creosote residue collects on the ﬂ ue lining. Because of soot and creosote build-up, it is recommended that the ﬁ replace and chimney cleaning be done twice a year. In colder climates, cleaning should be done more often.

Always allow the ﬁ replace to completely cool before you work on it, which means, of course, shutting off all gas and electrical connections, also.

Be certain that you use only solid fuel in your ﬁ replace. You may use a natural or LP gas log lighter as a method to start your wood ﬁ re.

The ﬂ ue damper must be in the OPEN position whenever there is heat in the ﬁ replace.

For the spark arrestor, scrub with a wire brush. To dismantle the chimney cap for cleaning of the ﬂ ue, unscrew the four screws that hold it in place. For cleaning access from below, open the damper in the ﬁ rebox. It is best to use a ﬂ exible handle chimney cleaning brush made especially for the job.

If your ﬁ replace system has any offset chimney sections, start cleaning with the ﬂ exible brush from the top of the section downward to the elbow. Then clean from the ﬁ rebox up to the offset/return section.

Be sure that you have covered the ﬂ oor of the ﬁ replace and out to the hearth with a damp sheet that has been taped securely in place. When all the soot has settled, remove the sheet and vacuum up – don’t sweep the excess soot.
