ONYX2 Owner's Manual 

RSF Woodburning Fireplaces 

 

If you have purchased the central heat kit option or the circulating internal blower, make sure the blower is off 
before opening the door.  

 

Check to see if other fans in the home are running, particularly a kitchen range hood, or bathroom exhaust 
fan. This can affect the pressure in the home. 

 

Try opening a window near the fireplace a little, this will equalize the pressure in the home and should correct 
a draft problem. Once proper draft is established the window can be closed. 

 

Make sure you’ve used enough kindling to establish a hot fire quickly. The most likely time that smoke will 
enter the home is during the lighting process. 

MAINTENANCE 

GENERAL CLEANING 

The high heat paint and plating can be cleaned with a soft damp cloth. Use a mild detergent and water. Do not 
use abrasive cleaners. 

PAINT 

You can touch up the face of the ONYX2 with 

Stove Bright 

Metallic Black high temperature paint which is 

available at most fireplaces dealers. Follow the directions outlined on the spray can. 

DO NOT 

attempt to paint the 

fireplace while it is still warm. Keep the spray can away from any source of heat or open flame. Ensure that there 
is adequate ventilation in the room from the time you start painting until the paint is dry. 

Stove Bright 

is available 

in a wide range of colors if you want to change the color of your ONYX2. 

We recommend that you take the time to protect or remove any item that you do not want to paint such as: the 
door glass, the plated door, the fireplace surroundings, etc. The glass can be removed from the door but you will 
have to replace the window gasket. 

GLASS CLEANING 

In a controlled combustion firebox, temperatures are not always high enough to keep the glass perfectly clean. A 
good hot fire once a day usually cleans off most of the deposits that have accumulated. Remember: the drier the 
wood and the hotter the fire, the cleaner the glass. A word of caution: although heat will not break the glass, 
impact can. Be careful not to hit the glass. 

™

 WARNING: NEVER CLEAN THE GLASS WITH AN ABRASIVE CLEANER. USE ONLY A CLEANER 

RECOMMENDED BY YOUR DEALER. NEVER CLEAN THE GLASS WHILE IT IS HOT, A SERIOUS BURN 
CAN RESULT. THERE ARE A NUMBER OF EXCELLENT WOOD STOVE GLASS CLEANERS AVAILABLE 
WHICH ARE FAR SUPERIOR TO REGULAR GLASS AND OVEN CLEANERS FOR WOOD STOVE 
APPLICATIONS.  

CHIMNEY CLEANING 

Check the chimney for creosote buildup every week or so until experience shows how often you need to clean it. 
A buildup of ¼" or more should be cleaned before more creosote accumulates. Use an 7" round brush. The baffle 
in the firebox can be removed to gain access to the flue from below.  

Follow the directions in the Refractory Brick Installation section to remove and replace the baffle. If you prefer, 
you can simply lift the baffle and move it forward and let the debris fall in the firebox. Do not forget to push the 
baffle back in its place after cleaning the chimney. This second option is easier than removing the baffle. 

DISPOSAL OF ASHES 

Remove the ashes before they become too deep, i.e., before you have a spillage problem when you open the 
door. 

The ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be 
placed on a non-combustible floor or on the ground, well away from all combustible materials pending final
